Topping D50s vs DX3 Pro

Thank you! Wow that's big, I expected a similar form factor to the original power adapter, only more powerful.

Do report back please!


Will do. I bought the LPS for my Topping D50 from the same eBay seller. It made a positive difference to my D50 and I'm really loving the sound from it. Hopefully the DX3 Pro will sound even nicer with this new LPS.

Topping D50s vs DX3 Pro

I'm really not sure which is better after more listening today. The Topping D50 was more 'airy', had more detail and had a much bigger soundstage than the DX3 Pro. I was able to place instruments more accurately with the D50. The DX3 Pro sounds a bit more compressed but is a little more musical. It is able to bring the entire composition together better than the D50. You still may want to try the D50 as you may prefer its sound. It's a different sound. The D50 was with an LPS so I need to wait to get my LPS for the DX3 Pro before I can do a more fair comparison. Also, the D50 had a few months of use and the DX3 Pro has only one day of use so I need to burn it in sufficiently.

I will need another couple of weeks to decide which one I keep in my headphones system.

I did experience a burn in time with the DX3 Pro where it started off real strong and then got a bit dull and flat for quite some hours. After which it opened up again. I never am a big believer for burning in DACs or headphone amps... (Headphones and speakers with mechanical parts I do believe need to burn it) but this thing did seem to need some time to settle.. Now I have my fully tuned and customised ES9018 DAC next to it with dual AD828 opamps in class A. And i'd have to say the 9018 is wider in sound stage and has that typical ESS sparkle but less detail and depth. Less musical. The DX3 Pro is my easy choice to go to for daily listening. It's well balanced and maybe not having that sparkle that I've come to love from ESS chips but a solid well rounded ans detailed sound. My ES9018

Topping D50s vs DX3 Pro

It's hard to explain differences in sound signature between different devices into words. All I can say is that my fully babanced LKS ES9018 DAC has withstood the comparisons to other more expensive DACs and came out ahead most times. But this little DX3 Pro gem practically made it obsolete in my desktop setup. I have no reason to turn it on anymore now the DX3 Pro shines on my desk. It's just a darn good DAC in a super small package with tons of features! I'd warmly recommend it to anyone looking for an all in one option since it's very capable of doing all well.

DO KEEP IN MIND I am running it with the 15V/1.5A LPS. And it DOES increase the lower end of the frequency spectrum ofthe head amp drastically. But couldn't find the same improvement when using DAC only. For everyone that's going to use the head amp out I would heartily recommend a solid low noise LPS.

Topping D50s vs DX3 Pro

Have any of you tried checking if there is a difference between using the front 3.5mm jack and using an RCA Y splitter adapter with 3.5mm input in the back? Are both RCA and 3.5mm amplified the same way? I'd prefer to connect the headphones from the back instead of having the cable on the desk.

I don't think that would work. The RCA outputs on the rear of the unit are line outputs rather than headphone outputs.

Topping D50s vs DX3 Pro

One other improvement I made today in the configuration of my DX3 Pro was to use Preamplifier mode rather than DAC mode. It's essentially the same thing apart from the ability to use the volume control on the DX3 Pro. DAC mode provides a fixed level output on the RCA sockets. Preamplifier mode allows you to vary the output volume presented at the RCA sockets. I'm using an external headphone amplifier and having full line out seemed to be stressing it a little (as was also the case with my Topping D50 DAC). I lowered the volume on the DX3 Pro to -3.0dB (to match what I was using with the D50) to make a fairer comparison and the sound does seem to have opened up slightly, and I had to increase the volume on my headphone amp slightly to compensate. Of course, I will listen for a few hours at nighttime when there's very little ambient noise to see if this has improved the sound or not.

Topping D50s vs DX3 Pro

Topping DX3 Pro vs Topping D50 After several more hours of listening via the Topping DX3 Pro, I went back to the Topping D50 to check on several things. I have to say that at the moment, the Topping D50 sounds better to me in terms of overall sound quality. Firstly, the reference track I used was a 44.1kHz/16-bit version of "Soul Embrace" by Brian Simpson, and you only need to listen to the first 30 seconds as it will reveal the issues that I had with the Topping DX3 Pro. It's a track that I've listened to more than a hundred times already so am very familiar with it. I also used several 'bass test' songs via Tidal. I've been listening with my beyerdynamic Amiron Home headphones that are far more revealing than my speaker system. Whilst I was listening to the track via the Topping D50, I noticed that something was missing. With the D50, the first few seconds of that track have bass drops that I feel in my chest even when I'm listening via headphones. I started to notice that this chest-thump was missing via the DX3 Pro. I listened to the same portion of the track several times to confirm this. When I put the D50 back into my headphones system, that chest-thump returned. I then searched for 'bass test' songs in Tidal and noticed that some deep bass was entirely missing on the DX3 Pro - I simply couldn't hear it! This surprised me quite a bit so I listened to the same 'bass test' tracks using the D50 and I could hear the very low bass through my headphones. It appears that the DX3 Pro's analogue output stage has a narrower frequency response than that of the D50's. Put another way, you can hear much deeper bass with the D50. Next, that song has some sharp piano sounds. When the keys are hit, it's as if someone is tapping the inside of my skull when listening via the D50 - the sound is so sharp. With the DX3 Pro, that 'tap inside the skull' sharpness was missing. It was a little dulled and veiled. I also noticed that the treble on the D50 was a lot more extended and clearer. Finally, that song has several musical instruments that I could place on the soundstage easily with the D50. With the DX3 Pro all of the instruments were closer to the centre of the soundstage and it was more difficult to separate them. So the D50 was the clear winner. Almost. Where the DX3 Pro shines is vocals. Female vocals on well-recorded songs are simply magical. The vocals are forward on the DX3 Pro and the musical instruments appear to be behind the singer. On the D50, the vocalist is presented further back, in amongst the instruments. So, it's a tough one! I'm going to repeat this testing again when the LPS arrives. However, for now, the Topping D50 has a significantly wider frequency response that can actually be heard, separates instruments better and places those instruments in a more well-defined soundstage.

The DX3 Pro is missing low bass frequencies, produces a narrower soundstage, puts the instruments together so it's difficult to separate them. However, it produces captivating vocals where you feel as if the vocalist is singing right in front of you.

Topping D50s vs DX3 Pro

Hi all, Just a warning: if you connect your DX3pro (previously set in "preamp" mode) directly to your AMP you may have a big problem : I someone press the LINE OUT button or double click on the volume button (knob), then your DX3Pro switch from "preamp" mode to "DAC" mode and the full signal (at -0.0dB) is sent to the Amp...i let you imagine the consequences.... apparently i'm not the only one to report this issue...

What can we do to make TOPPING sending the Alternative firmware (or to propose a way to block the Preamp mode via the PC driver interface) to fix this "bug" for the ones who want to use DX3pro as a preamp ?

Topping D50s vs DX3 Pro

Yes, do test again with the LPS in place. You might be surprised. Apart from that. I do know what you mean by the DX3 Pro having a more centered sound and more pronounced vocals. I like listening to female vocals so clearly this has it's benefits. Also I pair it with a Lehman with Burson V6 discrete opamp. Which in turn does open up the sound. Without the Lehman the DX3 Pro outs are a bit more narrow and less sparkly. If I compare it to my ES9018 I can clearly understand the difference described between ES chip and AKM. The AKM is more neutral and calm to my ears and forward. Where the ES is more wide and spacious but between my devices lacking a bit of detail and body because of that. So I prefer the DX3 Pro. Depending on which headphones you pair it with and which genre that is. It also comes down to synergy between devices. But in terms of detail the AKM hasn't dissapointed at all. It's my daily driver. I do will invest in getting myself a D50 too to play with it a bit more to replace my ES9018. THANKS for sharing your findings.

Topping D50s vs DX3 Pro

I'm going to embark on a mission. Since I really love the sound of the DAC but admit there is some room for improvement regarding widening the soundstage a bit and making the sound a little more spacious I have decided to solder out the OPA 1612 which is a very neutral and clean sounding opamp and actually one of the better opamps to use nowadays in these type of stages. But from my experience rolling the OPA 1612 against others opamps in my LKS 9018 DAC, I know it can be improved. How can it be improved? Well for starters class A could help but how about a discrete opamp... Since it's just one position to fill the upgrade won't be too expensive but might be well worth it. How about a try and ordering me some more opamps to play with. The luxury ones that is! But there are several problems I run into. One is that it's a sop8 socket and all discrete opamps are dip8 which obviously brings us to the next problem. And that's the limited space. Since I'd have to convert the socket from sop8 to dip8 and with the limited space available that will be a bit of a challenge. Obviously, for testing purposes, I want something easy to access and swap and if I like it I'll solder it in more reasonably permanent as close to the PCB as possible. So here is what I measured and came up with. From the PCB to the top of the housing there is 21mm of space. this space is for some sort of adapter from sop8 to dip8 AND the opamp. Let's start with finding the smallest possible solution for converting the socket to dip8 so there is more to choose from considering opamps.

Topping D50s vs DX3 Pro

These are the options for converting SOP8 to DIP8 and I've ordered them all.

The first one and second one are most appealing as it seems. But I ordered all the options to pick the best quality and functionality from them. Next, we need to choose an opamp that is actually an upgrade over the already pretty darn good OPA1612A. I've got a Burson V6 laying around but it's currently having a duty in my Lehman as headphone amp and pre-amp which is doing a darn fine job there. And it's obviously too tall to sit in straight for sure. But Burson does make these pretty solid wire extension sockets as can be seen below and I already possess a few of these.

Topping D50s vs DX3 Pro

Opamps to choose from that have my attention: Burson V6 Vivid Dual Sparkos SS3602 L.K.S Audio Pure Armor I'm already in possession of the Burson V6 Vivid Dual to swap and test and I ordered the Sparkos SS3602 for 700 RMB (€90.... yes I KNOW. But I wanted to give it a run in my Lehman too and having another top notch opamp laying around can't be harmful. I'm not claiming anywhere it's the most cost-effective solution or that it makes sense to roll a €90 opamp in a €140 euro DAC, yes I paid just €140 for it!)

When talking about size the Sparkos will be the most favorite if I can get it to fit just inside the case horizontally. All opamps and sockter convertors are on the way and will arrive in a day or 2 I assume. By then I'll start preparing to do the surgery and see if I can squeeze some more performance out of this puppy or if it's already near it's max. Either way it will be a nice experiment and if it doesn't work out as planned I'll at least have some more nice opamps to roll through my Lehman or other DACs.

Let me know what you think. I appreciate the input.

Qudos to you for seeking further improvements of this DAC! Your post is way beyond my technical knowledge but I'll be very interested in any changes and improvements you make.

Topping D50s vs DX3 Pro

More Topping D50 vs Topping DX3 Pro My linear power supply for the DX3 Pro arrived today and I replaced the Topping D50 in my computer based HiFi system with the DX3 Pro + linear power supply. I'm listening to it as I type this post. The sound is beautiful. I preferred the Topping D50 in my headphones system. However, I prefer the DX3 Pro in my speaker-based system. Equipment used is:

2017 iMac running Tidal HiFi > Fisual Havana USB 2.0 Cable 0.9m > Topping DX3 Pro + linear power supply > Audioquest Tower twin RCA to 3.5mm jack 0.6m > Ruark MR1 Mk2 active speakers + BK Electronics XLS200-FF subwoofer connected via a Fisual 1m Havana XL Subwoofer Cable

In effect it's a 2.1 speaker system. Settings on the Topping DX3 Pro are:
  • Input mode: USB
  • Output mode: DAC
  • PCM filter: F-3
  • Screen brightness: L-1
  • Auto power: A-O
I had to turn the subwoofer gain up a tiny bit - around 2-3 degrees of the rotary gain control. The mids are more forward. Vocals, once again, are beyond imaginably good! Listening to Lindsey Webster singing "Those Three Words", it seems like she's in my listening room! Vocals are very, very smooth. Now I hear the 'velvet sound' of the AKM DAC chips in the DX3 Pro. Treble is a little further away. Pausing the music and holding my ear to the speakers and subwoofer, all are 'dark' with no interference noise. Soundstage is a little narrower than the D50 (as was the case with my headphones system), and instrument separation is less too. Overall, the sound is very musical and great for me as I work from home a lot so it's lovely to listen to for several hours a day. It's nicer to listen to for long periods - less fatiguing.

I don't know why the Topping D50 sounds better in my headphones system and the DX3 Pro sounds better in my speaker-based system. It's just the way it is for me. YMMV.

It's more like hobby than that it makes sense haha. The OPA1612A is already a really good opamp. I am guessing the improvement will be marginal but audible. I'm hoping to open up the soundstage a bit more. From what I've read the Sparkos discrete opamp is practically the best there is. And since the DAC is not really struggling with much else hanging behind a quality LPS and with the guys from topping knowing what they are doing. Rolling in a top notch opamp seems to be one of the improvements that can be made for a slightly different sound signature.

One other thing is might look into is decoupling with some elna silmic IIs

That is exactly what I thought of the comparison with my LKS 9018 and the DX3 Pro. I did feel the ES9018 was doing a bit better job at my Mad Dogs and Aeon giving it a bit more sparkle and soundstage. but for my studio monitors I'd pick the DX3 Pro any day any time.

Topping D50s vs DX3 Pro

I broke my board with trying to solder the sop8 to dip8 adapter on. The plating on the board came off and it's too small for me to fix. So I ruined a perfectly good device. Ordered a new one to do another surgery on. I still believe in the mod. I might ask some help of my friend who's better at small soldering work than me. My eyes can't keep up with the small work.

Be warned to do mods haha. Post back soon when the new device comes in.

New board on the way from the Topping factory. I contacted them from their official Taobao shop and the board should be in the day after tomorrow. I also ordered a brand new original unit to compare with. The replacement board I will continue modding but the original unit I'll keep original and see how the mods will work out fast switching between them in listening tests.

Sorry to hear things gone wrong with your promising tentative to improve this very good kit. wouldn't we be more efficient if we could make a list of all the improvements we expect TOPPing to make on this DX3pro ? at least we already have 2 easy ones with great return (see my post on preamp mode which is not secured + your AOPs upgrade...) does this make sense ?

my 2 cents.....

I would like to add the following refinements:
  • Volume levels should be preserved for each I/O combination when switching between them during any listening session.
  • I/O volume levels should be saved as “presets” with a long press of the multifunction knob. The presets would be the levels that will be used for each I/O combination when returning from standby.
  • I think fixed DAC mode (0 dB Line Out) should be optional (and variable the default), with a toggle available in the settings configuration.

Topping D50s vs DX3 Pro

So far the mod cost me €80 for the discrete opamp and €100 for a new board and some loose components. I can't really advice it to anyone price effectively! But I've already gone through most of it so let's finish it and report back if it's worth it or not!

Puzzle

Best option for low profile and good connection and swappable. It's not the prettiest and I'll need to be careful to not swing it around...

Needed some modification. Combining parts of all different options and finetuning so it would just fit.

Might need to put a piece of isolation tape over it to be sure. But I'd prefer not to since it will obstruct with releasing it's heat. In about 2 days I'll be able to give my listening experience between modified and not modified. What I hope to hear is more defined bass and a wider sound stage. The comparison between the DX3 Pro and my LKS 9018 Model II is that indeed as described above between the D50 and the DX3 Pro. Where the DX3 Pro has better vocals and more forward mids, it lacks in the lower regions. Just doesn't have the oompf I'm used to from my studio monitors and headphones. Also the sound stage is quite a bit narrower than the ES9018. I do think this is chip flavor and less output stage flavor.. since both DACs use OPA1612 from factory.

I haven't seriously listened to the Sparkos opamp yet since my Lehman is running fine with the Burson V6 but I'll be rolling them against each other in the DX3 Pro to see which one will pair nicely.

The oompf and sound stage are most probably not to be altered that much by opamp rolling but by improving PS decoupling between channels from the DAC chip down stream just my 2ct Looking forward to you findings at your second attempt

Agree with you. I asked topping for schematics but don't think I'll have much luck with that. For now the most simple mod I can do is rolling the opamp for a discrete one to refine everything a bit. Let's be clear about my intentions here. Seeing how I already threw about 4000 RMB (€500) in total on this little project breaking one board and ordering another unit for comparison it's nothing that makes actual sense. For 4000 RMB I could get a really slick DAC with a better power circuit etc. But the performance of this little gem has impressed me a lot that I wonder if there's more to be gained from it. I could have probably better waited for the D70 if I wanted better performance out of the box.

Anyway it's just my curiosity at play here.

Topping D50s vs DX3 Pro

Here a photo of the damage I had done to the socket when I accidentally pulled the dip8 convertor off... being tired and impatient..

Topping D50s vs DX3 Pro
I send the board to my friend that will tinker with it and can probably fix the opamp socket by pulling wires straight from the resistor positions. I ordered him a new display too so he can play around a bit and come up with useful modifications. I myself started burning in my new original unit since yesterday morning, which I won't modify to use as reference for the mods I'll do on the new board I got in today. I did modify the new board properly today. Here are some photos of process and result. removed the sop8 opamp properly.

The result

I just fits. But to be safe I put a little bit of black isolation tape on the case to not shortcut the opamp... (costing €80 this would be a shame)

Topping D50s vs DX3 Pro

More mods coming. Tomorrow I'll be testing it. The opamp also still needs to be burned in properly so it will be a while before I can give a proper conclusion if the mod was useful or not.

I could use it on two of my devices..A solid state headphone amp and my DX3 Pro? Do you think it would work as well as the one you recommended? It states that it will supply , and for my SMSL sAp II it will supply which is double the amps required. I'm a noob so please forgive my knowledge gap. I asked about the one you recommended and I got back reply that it is too much money and they recommended going with a cheaper Meanwell. I'd like to have a backup in case my existing power supply fails and also see improved bass quality. I feel that I prefer the one you recommended. I'd just like to see what you think of this variable voltage unit. Thanks in advance.

Another thing this one has going for it is it can be operated worldwide on 115V/230V. AC

Yesterday, I noticed that I lost USB audio output from Windows 10 on my DX3 Pro. The display indicated that it was switching to the desired sample rates, up to the max. PCM rate, but there was no audible output. BT audio was working fine.

I rebooted a few times, to no avail. When I checked the Windows Mixer (which did indicate positive unmuted signal levels for System and iTunes), I noticed that Skype had been stealthily installed on Jan. 29 (by Microsoft) and was one of the sources. I uninstalled Skype, and my USB audio became audible again. Did anyone else see this?

Taz777, could you plug your headphones directly in the DX3 Pro, without headphones amp, and test it like that?

Because the headphones amp of the DX3 Pro is said to be very good!

I tried this today and listened to a few songs from Tidal HiFi. The DX3 Pro was put into headphones mode with volume set at -38dB (<-- very important to set the volume low to start with BEFORE plugging in your headphones!). I used my AKG N40 IEMs with a fairly decent MMCX cable. I played three HiFi tracks from Tidal, and one Masters track. Initial impressions are that it sounds pretty good! There is a good amount of bass. Treble is slightly subdued, but that may be the IEMs. Layering is a not as much as I'm used to. Increasing the volume to -30dB makes the music quite loud, but also adds a little more dynamics to the sound. Vocals are just ever so slightly 'cloudy'. There's a pronounced mid-bass underlying every track that can sound good or bad depending on the song. It's a very comfortable sound to listen to. I have a much higher resolution dedicated headphones system so I'm comparing against that, so some of the criticism may be a little unfair. All in all, for what you get for the money, the DX3 Pro's headphone output is pretty good. It doesn't quite grab me or amaze me, but is pleasant. I could listen for hours so it's not tiring. The overall signature is 'rounded'. It could do with a little more dynamic range. I don't think anyone would be disappointed with the sound quality from the headphone jack of the DX3 Pro given just how much capability is packed into the little unit at such a great price.

I'm happy to try one or two other headphones if you want me to as they may match the DX3 Pro better than the AKG N40s.

Topping D50s vs DX3 Pro

Thank you very much for your review Taz777. I have two pairs of headphones: an AKG K701 bought 15 years ago and a brand new Magnet LZR 980, both very nice and complementary. As for a dedicated headphone amp, I heard about the JDS Lab Atom Amp. Do you know it? For my speakers, I have a Topping D10 DAC plugged in my solid-state amp. Do you think it would be a better move to get the JDS and feed it with my Topping D10, or to replace both by a DX3 Pro? (and I could still cross the JDS Lab via its RCA output to reach my amp for speakers listening)

Cheers

I have the D10 and the DX3 Pro. The JDS Atom is known to have excellent measured performance, but the DX3 Pro isn't too far behind for most people. I think it comes down mostly to features. The D10 is basically a DAC/USB bridge, and the DX3 Pro is a DAC/amp with a remote and several digital input options (USB, 2 S/PDIF, optical, Bluetooth), and no digital outputs. If you don't need the extra features of the DX3 Pro, you could get the JDS Atom for ~$100 less, and not have to disposition the D10.

Personally, I've found that I like the remote and Bluetooth options of the DX3 Pro, so that's what I'm using. But now I have to do something with the D10 while it still retains some value.

I do not know about the JDS Lab Atom Amp. For my headphones system I'm using a Topping D50 DAC feeding an Arcam rHead headphone amplifier. That combo sounds very beautiful to my ears. For my desktop speaker system, I'm using the DX3 Pro feeding Ruark MR1 MK2 active speakers + BK Electronics XLS200-FF subwoofer. I found the DX3 Pro sounded better in my speaker-based system than in my headphones system.

I'm a big fan of having separates for as much as possible as you can slowly upgrade individual components, so I would favour feeding a headphone amp with a DAC. You can then also play with cables to find the sound that you like. However, everyone's tastes are different and you may find that the DX3 Pro sounds great as a DAC, headphone amp and line out to an external amp.

Topping D50s vs DX3 Pro

DX3 Pro is an amazing device after you do a few mods if you can! I've done a few "simple" mods and the device got a serious league upgrade. It outperforms my highly tuned LKS ES9018 easily. The ES9018 uses only high-end components and CCS on I/V stage. The AK4493 has better detail, better imaging, better instrument seperation better vocals.. just more holographic. One thing it's lacking is bass. But i'm on the road figuring it out. Probably need to upgrade the PSU a bit here and there. Most important mods were: Sparkos SS3602 opamp. Which improved everything a lot! but I am guessing this is because class A bias. Biasing another opamp should do the trick too.

Topping D50s vs DX3 Pro

Replaced 33uf DAC chip output caps with 100uf KEMET KO-CAP poly caps I put the 33uf cap coming from DAC output in the 10uf position on opamp voltage rail but I'll replace it later. remove ceramic AND tantalum and put a electrolyte nichicon KZ.

did topping release a fix for all the problems related to the dx3 pro? like hanging and units just dying?

Topping D50s vs DX3 Pro

It's not a software problem but physical problem with bad soldering on the opamps. So if you suspect to have this problem the unit need to be returned. I guess you can fix it yourself if you know how to solder and to identify the components.

pass, It's is their job to do the QC stuff not the consumer, it seems like its the trend with these chinese companies to use the public as their test bed instead of spending money for their actual RnD, what a load of crap from them.

Topping D50s vs DX3 Pro

I personally find the Mackie MR524 or the MR624 active monitors to sound much better than the PreSonus Eris E4.5.


Are they also entry-level and affordable?

The Mackie MR524 is very good value considering it's very good sound quality. It's currently going for $150 per unit, so it's about $300 a pair. This should should pretty much be in the affordable entry level category.

Hello everybody. Could anyone having the DX3 let me know if I can switch on/off the unit with my UPS? I currently have a UPS connected to my computer which controls a number of secondary mains sockets. When my computer is powered on, the UPS subsequently wakes up a number of specific devices like the USB Dac and my B&W powered speakers. My question is, will the DX3 wake up when the PC is powering on or do you have to switch it on/off solely using the remoter controller?

Many thanks!

Hello, I am thinking about one of these units and want to ask a couple of questions: 1. Is the Bluetooth feature both to Receive AND to Transmit Bluetooth? I am wondering if I can use this unit and send LDAC signals to my wireless LDAC headphones? I assume it can receive signals from a DAP.

2. I am wondering if anyone has an opinion of the sound quality if this DAC vs the D10?

How does this stack up compared to an odac/O2 combo unit? What's changed with the v2 version?

I am also curious about other DAC+HeadphoneAmp units out there compare to the DX3 Pro. This is a nice unit, but has a few warts...

Somehow the volume is very low, no matter what I do.

Running on USB mode with Windows 10 and headphone mode.

Been pretty happy with the device. No loud pop as with the Schitt stack, and the screen has been more useful than I thought. Odd you have volume issues - are you using Windows and device volume in tandem?

Yes windows volume is already on 100%.

You can also try adjusting the gain by using the M button on the remote control. Low gain is 0 db and high is 9 db.

To use the remote you need to buy a CR2032 battery, which should be included but is not.


I have tried gain mode already. It does increase the volume of course but not by much. Windows volume is on 100%

Hey Bro, you have not said what your problem is, how you are using it and what you are pairing it with? You have not bothered to fill in your profile for us to see what gear you have and what your budget is, so are we expected to read all the cryptic clues that you may bother to share with us?

Are you saying that it is not powerful enough to blow your ears to smithereens?

I have tried it with various IEMs, like the Vsonic GR07, Tin Hifi P1 and KZ ZS10. Also tried the line out to my speakers (some random Sony speakers). With all of them, the volume is really low. Are you saying that it is not powerful enough to blow your ears to smithereens? <-- Sorry, that is just a really silly question. I don't need to have it blowing out my ears to say that the volume is low.

Anyhow, I have already contacted Shenzen Audio (the seller), see what they think.

Anyone here know how to enter the options menu with the remote? The manual says there are 2 ways: 1st by holding down the knob while plugging the power cable in, 2nd with the remote but it doesn't give specific enough instructions for that. Any ideas?

Any luck so far? Maybe if you mentioned what you are trying to achieve, some of us can help you. BTW, I reckon that the DX3 is a cracking DAC but the headphone section is quite lacklustre to my ears. I am mainly using mine as a DAC powered with a 12 volt car battery into a good speaker system. I prefer it to the DAC in the Sabaj D5 (but not the HO section) and also IMO it is way better than the SMSL M10.

I now have mine about 4 weeks and with plenty of burn-in time, so my opinion is well formed. I reckon that the included 15 volt (switching) wall wart power supply is a weak feature, so I suggest changing the power supply to a good laptop type which should improve the sound for most people's ears.

No luck yet. my issue is with the unit auto connecting to all the bluetooth device that enters pairing mode. Was trying to figure out a way to manual switch off bluetooth so it wouldn't do that but at the same time want to be able to switch it back on without the knob holding / power cable plugging method.

Just bought the DX 3 and am wondering what the correct volume settings are. I have only used USB powered dac amps in the past like the Dragonflys,and have set my laptops hardware volume to 100%,and used the software music player for volume control.

Am I correct in saying for the Topping I should have both the hardware and software volumes at 100%,and just use the Toppings volume control only.I have read through a few threads where some say set the software volume lower than 100% to avoid clipping,but the Topping at least doesn't appear to have clipping problems.

Yes, set both to100% and if you don't have any issues just leave it that way. I believe the output is only about 2 volts, so it should not be an issue for any other gear that you connect to it. BTW, I still reckon that the DX3 is a cracking DAC and great value......................................

I was using the Topping DX3 Pro (v1) for some time and was quite happy with it's DAC and amp section driving my Sundara but felt that it's still missing that last drop of juice at high gain therefore I decided to add the JDS Labs Atom to take over the amp section and couldn't be happier. Although on paper the Sundara looks pretty easy to drive with it's 37ohms impedance but unfortunately that's not the case due to it's low sensitivity. I need to switch my DX3 Pro amp section to high gain to drive the Sundara to an acceptable level but unfortunately the DX3 Pro strains a little when you drive it to it's limit. The JDS Labs Atom now takes over the task of driving my Sundara while the DX3 Pro is in dedicated DAC mode. My Sundara is now driven to it's full potential with the Atom in "low" gain without breaking a sweat and sounding wonderful. This is my personal experience with the DX3 Pro paired to Atom driving the Sundara therefore this might not apply if you use more efficient headphones that are not as power hungry like the Sundara.

If you're looking for more power than the JDS Labs Atom then you might want to consider the Monoprice Monolith THX AAA 887 which support balanced output as well and definitely much better built than the Atom.

just an fyi, I broke out my dx3 pro cause my monolith 788 is in for RMA and flashed the e30 firmware v1.08 on it thinking it was the right firmware and it works still. my system sees my dx3 pro as a e30 dac now. not sure if there is any improvements but it works.

Hi Everyone

I understand what you are referring to, as I also have the same issue. The bluetooth seems to have a predatory instinct to command the entire world! So far, the only way I know how to turn it off is to "remove device" in bluetooth settings and then set it up again when needed, which is far from ideal.

BTW, I reckon that the SQ over bluetooth is surprising good and is a very handy feature to have.

I just picked up a DX3 Pro LDAC from APPOS about 10 days ago. Primary intended use was as a BT receiver so I can listen to music somewhere other than the office chair/desk that I sit at all day for work. I definitely experienced the "predatory instinct" regarding BT connection as well, and also had to remove device from my phone and iMac after each connection. Otherwise, it would constantly reactivate on its own accord. However, I now I have a new wrinkle/problem regarding BT. My unit indicates that it is connected via BT to "something" but not any device I have in my apartment. I cannot get it back to a "pairing" or blinking icon status. Been forced to move it on to the desk. Have it connected via USB to iMac, pushing out 768.0 kHz into a pair of Sennheiser HD 560s, and at times I will line out into a Schiit Vali 2+.

Anyway.....this is if my first dip into 'higher quality' audio and I love this little unit. But the BT obstacle has really put a damper on the overall functionality.

The Playstation4 seems to have an optical out, if so you should be able to use that? No, you can't use a USB powersupply. It needs 12-15 volts and has a dedicated power input socket.

BTW, I have 3 Topping DX3 Pro (mk2) in my house and I will use them until they break. I use the bluetooth function on the one I have in my wifes kitchen and I find it surprisingly good. I feed it a BT signal from a BT 5.0 USB transmitter dongle in my laptop.

Hey, thanks for your reply. Yes, the PS4 has optical – so that would remove one cheap dac from my desk – but the PS5 doesn't and at some point Sony might actually be willing to sell me one so it would be nice if it worked with consoles, though it probably should.
Shame about the PS issue, did you upgrade the one it came with? The AQVOX supply was quite the upgrade to running the M2 straight from the Mac.
