I'm sure @amirm would test one if someone sends him a Topping DX3 'v2'.
If Amir is so inclined, I'd love to see objective measurements of the two headphone amps. I just purchased the V1 from 'Drop but received V2 and as I use it solely as a DAC+Headphone Amp I'm curious. In truth, I doubt my ears could tell any significant difference especially with my mid-range cans (HD6XX, HD58X, 'Austria' k701, etc) but where's the fun in not obsessing?!
Hat's off to Topping for addressing their users' issues!

Press the LINE OUT button for DAC; once for pre-amp mode with volume control, second time for line passthrough (fixed max volume), press button with headphones to go back.

To cycle through sources with the remote, just press the left and right arrow buttons on the remote.
Its the remote that doesnt work but ive figured out how to use all functions without it.

Good to know, thanks. mine has both stickers.

Because my remote is faulty how would i go about getting a replacement from a company like topping in china?

not sure as to get a replacement for free but if you don’t mind spending like 25 USD more, the DX7 remote is available for sale

thanks to this thread I recently ordered a DX3Pro V2. After an acciedently double push the dial and releasing the double mono amp onto my speakers I looked into the manual if there is a way to prevent that. It does not look like there is this "feature", isn't it?

Besides that I am very pleased with the silence from my tweeters! The power output with low gain mode on a 250 Ohm headphone is not enough, but on high gain its great. (Beyerdynamics DT880 Edition)

I ordered V2 because I want to use it with my 30 Ohm armature plugs KZ ZS-10 PRO and my 32 Ohm Sony MDR-XB950B1. To solve V2 high impedance issue I also ordered 80 Ohm impedance plug https://www.aliexpress.com/item/32892202826.html?spm=a2g0s.9042311.0.0.7c1033edmPik3h My V2 is on its way from China. Is it a good solution? I want to have good enough amp to be able to test and buy more advanced headphones, like LCD-2, or maybe Fostex T50RP MK3 or Hifiman Sundara. Now I only have Sony XZ Premium phone with 835 chip (no added amp) which has 24/192 direct mode and Fiio A3 amp. I have pretty powerfull 4 cores 8 threads i7 laptop and am going to use V2 in up-to DSD512 mode with some suitable for Win7 player. Also I consider using a balanced cable with V2. What do you think?

How do you know if you have a v2 model?

That's right. You can see a picture of the new sticker here.

Or you can open it up and compare the circuit board.

Most of the difference is on the inside. :)

There are some small functional differences in DAC mode, in the menu system, and in the user manual. Go here and here for the details.

Hello, I have been following the conversation surrounding this DAC+AMP for a bit now. Currently still thinking about going D10 + ATOM or just the DX3. I have a couple questions and I hope that some people in here can help me with those:

1. Is there any other way in which I can connect my phone (LG V30) to the DX3, other than using bluetooth? I was thinking about connect a USB-C OTG adapter to my phone and then the USB-B to USB-A to the OTG adapter. Would this work?

2. Suppose I do use bluetooth, would the audio quality be hindered in any way, as opposed to a direct-line-connection?

3. When it comes to audio quality, is the DX3 inferior to D10 + ATOM combo, if I don't need the extra power from the latter setup?

4. I am thinking about buying the Tin Hifi P1. Many have claimed that an AMP is pretty much a prerequisite for that IEM. Is this enough to drive it? (I'm just about 99.9% sure, but wouldn't hurt to ask if someone has experience with this).

Thank you for your time :)

Welcome to ASR.

1. Yes, it works fine using USB-C OTG and USB-A Male to USB-B Male to DX3.
2. Direct connection is better than Bluetooth in terms of audio quality.
3. No comments, have not hear them before
4. No comments, no experience on Tin Hifi P1 . however, the spec is like Final Audio E4000... at 95 dB sensitivity, 20ohm impedance , perhaps to get a decent DAP ?
