Topping DX3 Pro+ Review (DAC & Headphone Amp)

[pacorabanna]

Indeed you misunderstood. You just need to get into Settings mode: Power cord unplugged. Pressed in button while you plug in power cord. You should be in settings mode. If not try again until you do.
Then you cycle thru each settings with one press. Turn the know to select the value you need. Press/hold knob to save/exit.

Thank you for your guidance, it worked! I was able to enter settings mode and perform the required adjustments.
However, not having a remote and needing to manually change settings each time is somewhat inconvenient for me. While the sound quality does improve with the gain set to high, I'm not entirely satisfied with the DAC, especially when paired with my HE6se headphones. As a result, I'm considering returning the unit.

Hello everyone! I have been using the DX3pro+ for IEMs for two years. I recently wanted to connect a TV to improve the sound coming out of the TV. Fortunately, I read on this forum that the device does not really work well with the TV with a simple optical connection. That's why I was looking for a solution. I bought a 5 meter better quality audio coax cable and a digital to digital converter. This converter converts an optical digital signal to a coaxial digital signal. So the TV optical into the converter, and the coax from the converter into the DX3pro+. I mean it, the audio transmission works fine, so the device works perfectly with this solution.

Anyway, I'm satisfied with the sound of the DX3pro+ after I got it running properly (100+ hours) , it gives a full-bodied and quality sound for IEMs. I recommend it!

I've been using mine as a dac/preamp for a pair of powered monitors for about a year with TV sound via optical, and I've never had a single issue.

I just ordered the FiiO K11, it has USB-C, not USB-B. It is also 40 euro cheaper (amazon.nl).
(I do hope the logo lighting can be switched off)

The device arrived today.
The sound probably can’t be faulted, but there are clicks/pops when skipping tracks.

Thanks for this! I was considering the K11, and honestly it seems everything within this price range will work more or less the same.

What is the reason (in general) for clicks/pops when skipping tracks? I occasionally have that too but I blame the cabling (not the cables itself but maybe touching cables, etc.).

I didn’t know, so I asked chatgpt:

Clicks and pops when skipping tracks in a media player often occur due to the following reasons:

1. Abrupt Audio Transitions:
   • When the media player switches between tracks, the audio output may jump from one sample value to another without a smooth transition. This abrupt change creates a sharp discontinuity in the audio signal, which manifests as a click or pop.
2. Lack of Proper Crossfading:
   • Many media players use crossfading to blend the end of one track with the beginning of another. Without this, the sudden start or stop of a track can lead to audible artifacts.
3. Buffering Issues:
   • If the audio buffer is not properly managed when changing tracks, it can lead to gaps or abrupt playback, causing clicks or pops.
4. Improper Handling of Digital Audio Formats:
   • Some media players may not handle track transitions seamlessly due to differences in audio formats (e.g., sample rate or bit depth) between tracks, requiring a reinitialization of the audio stream.
5. Hardware Driver or Latency Issues:
   • Audio hardware or drivers might introduce artifacts during track changes if they do not process the transitions smoothly, especially if the hardware has high latency or poor support for rapid changes.
6. Signal Processing Artifacts:
   • If the media player uses effects or signal processing (like equalization or compression), these can sometimes introduce artifacts when tracks are switched.
7. DC Offset:
   • A DC offset (non-zero baseline in the audio signal) in one or both tracks can lead to a click when playback begins or ends abruptly.

Based on its answer I expected point 5 in my situation (recently changed to the FiiO which then introduced the click/pops).
I tried disabling upsampling (to 24/96) and the clicks/pops are gone; maybe it is a combination of 5 and 6 in my situation?
