Topping DX5 II

No problem at all about artistic choices and sound.

DC does not sound though. And that's exactly the problem, it can plague gear (recording or playback) and only a few will notice it without measuring, usually when stuff break, get hot for no reason, etc.

Edit: talking about vibe and trend, the latest is mixing white noise with the tracks. Imagine what happens to some amps and speakers up high with such a signal.
It moves the drivers out or in which can produce more and/or different distortion compared to no DC. So it can change the sound.

Not sure they know what they are doing, though. They probably don't.

Edit: I do not think this is on purpose, as they cannot know how the playback chain handles DC.

If it changes the sound in the studio, it might be a creative choice to keep it in place instead of using a high pass filter. Still, any competent engineer should avoid leaving it in not only for reasons of safety but also simply because translation cannot be guaranteed since different devices and speakers will produce different distortion.
 
I didn't see anyone actually measure this with multimeter yet so I did a quick test. While playing that YouTube video Topping DX5 II outputs upto 1.71 VDC from 6.3 mm connection with high gain and max volume. I used 100ms response time, i.e. output was 1.71 VDC for at least 100ms.

And is that good or bad?
 
I think this was talked about a while back, but can someone confirm is it, or will it be possible to equal the left and right channels independently like you can do on the RME?

Yes. That will be possible with the DX5 II
 
And is that good or bad?
That is really bad. Because you get significant level of DC at headphone out, while the correct behavior is DC protection should be triggered and your headphone output would be disabled. If you use balanced connection that is 3.4V DC. I don’t know which part of the music he/she uses. Though it has DC from the beginning, the level significantly increases after 1:00 in that song. If only the beginning part is tested, the DC level would go higher into the middle of the song.

Of course no one listens that loud, and the song is an extreme example of bad mastering. If you don’t listen to song like this you are fine. It’s just a pity that protection circuit is there but not working as expected.
 
I've been on vacation for the last week, and just got back last night. DX5 II was waiting for me on my return, and I set it up briefly last night, and spent a bit more time with it this morning.

On initial power on, it was detected fine by macOS and the VU meter showed an input source, but nothing came out of any input. Power cycling it resolved that issue and I've not seen it since.

I've updated the firmware to 1.39, but I'm still seeing the issue that after a power cycle all PEQ configuration set in Topping Tune is lost. The memory location created stays, but everything in that memory, its name and all EQ values are missing. Did anyone find a workaround for this yet?

Oh, and no import duties requested yet!

Topping Support said this will be fixed in 5-10 days. Many others also have this Problem.

Edit: you can edit the eq in the local config in topping tune and save it locally first. This way you just have to transfer it to the DX5 II instead of setting it up again when you restart the unit.

Ah, now that work around makes sense. I thought the work around was that it was saved correctly if you first created it in local and transferred it over. That didn't work for me, and I thought I was doing something wrong, but it seems that's expected.

I cannot use this work around because I use a Mac 99.99% of the time. It's not a big deal for me to move the DX5 II to a Windows machine to set up the PEQ with Topping Tune, but I do not leave it connected there.
 
I short of suspected that someone has messed with the track big time when I noticed that is a "remix" .

To save you the annoyance of moving the unit back and forth, VMWare Fusion was made free for personal use a while ago, and that's what I use on my Mac whenever I need to use Topping Tune.

Pretty sure that was changed when Broadcom acquired VMWare. I can't access Fusion for Mac, not without an account anyway.

It is $0 to create an account, and you can just create a dummy e-mail for that if you want. I downloaded it only a few months ago.

Thanks very much for the tip, and I'm sure this will help many folks, but unfortunately all of my Mac equipment belongs to my employer and the company policy is that whatever I install on my machine cannot be considered 'for personal use' because the machine is used for commercial purposes, even if my VMWare installation wasn't.

Pros and cons I guess... I get a near infinite supply of Apple hardware that I can use... but can't use 'Personal Use Only' software on it.

What I can do however is check with the company IT support to see if they have a commercial license I could use!
 
This also happens with the blue theme. So it might apply to all. I tried power cycling it yesterday up to 10 times and that did nothing, but when I turned it on the first time yesterday with the white theme as well as today with the blue theme, it was again the case. Power cycling the unit without changing the display settings does not fix it.
It does it only after mains power is disconnected either through the switch on the back or using a power strip regardless of whether it was in standby or on. It also did it for the orange theme so it is probably doing it for all except Aurora of course.

Also, occasionally it turns on when mains are connected even if it was in standby when mains were disconnected.
 
Though it has DC from the beginning, the level significantly increases after 1:00 in that song. If only the beginning part is tested, the DC level would go higher into the middle of the song.
The start (up to 0:27) and the very end are free of DC offset. The offset occurs from 0:27 to 2:30. Yet, my DX3 Pro+ did not turn off the headphones when playing this track.

Let’s hope Topping this time will be opting for vertical(!) fins or the crowd will go nuts again :facepalm:
It's not the crowd, it's the charts that back it up:
