Many people connect DACs to power amps or headphone amps. The volume control at the dac becomes the main volume control.Isn’t having a volume control on a DAC like having a volume control on a turntable or CD player?
I don’t get it.

Sounds exactly like mine.It's actually not incredibly hard to reproduce, as I just found. Just set the sample rate to 384kHz, bit depth doesn't matter. I put my phone to my headphone's ear cup to record it, here it is, an intermittent static buzz, for lack of a better description: https://1drv.ms/u/s!AptJOzTSXgG6ns8hqFQwKrcB6j0m4A
Is this what the rest of you are hearing? You may have to turn the volume up. Recorded while watching a YouTube video. Any clues what may be happening here, @JohnYang1997 ?
But that's not soundstage, that's simply channel separation. So unless you want to say channel separation is soundstage, then I suppose that's not what I assumed one talks about.
And when you say "less distortion and noise floor" increases soundstage. Well that's fine, but that then makes soundstage entailed by other concepts, but in tandem amount to a newly combined term like "soundstage". But if that's the case, then zero distortion and noise = maximum soundstage? So if I am playing a recording doing mono, or playing a recording done in a church binuarally (or lets say 7.1 surround sound). Both of them would have identical and maximum soundstage so as long as they both had something like zero noise and distortion hypothetically?
See why it's problematic speaking about soundstage in this way?
Interesting.I am not sure if this is a defect or what, but CS43198 doesn't really have what I would consider to be a functional digital filter at 384 kHz. I would not recommend using 384 kHz sample rate if you care about quality.
Interesting.
In the latest firmware update (2.44) a number of completely new filters were added, which from what I understand is not in the chip itself but is an addition made by Topping. How do they work compared to the filters that connect to the chip itself?Page 130 of the datasheet shows the response in octuple speed mode (384 kHz). Apparently AK4490/3 behave similarly above 192 kHz. Not sure about AK4499 or ES90xx. I think this is why it would be nice to see just a couple tests at higher sample rates, because some people actually use them even if they don't bring audible benefit.

We are preparing a firmware update. Hopefully it will fix the 384KHz play back issue for everyone.I'd really appreciate your input on this noise issue some of us are experiencing. Can we pin this on a defective unit, is the DAC not playing nice with Windows?
I've said before I bought Topping because of this kind of openness and interaction with the customers. I really liked this from FiiO back in the day, really like it now, so I'll wait. Hopefully the update will fix it!We are preparing a firmware update. Hopefully it will fix the 384KHz play back issue for everyone.
For those who are thinking returning the unit, I'm not here to say these things to stop you from returning. You gotta do what you gotta do. If you believe in us, you can hold on to it and wait for the update.
Sometimes it takes 3 to 4 hours to appear.The noise error appears to be related to some copies of the D30Pro. It seems to be a manufacturing defect rather than a design defect. I do not have this problem with my D30Pro.
I'm keeping this if this is a software issue and it can be solved by firmware. Thank you for replying in this forum, much appreciate your support.We are preparing a firmware update. Hopefully it will fix the 384KHz play back issue for everyone.

Hello John, may this Firmware Update also solve the music interruption issue which some (including me) reported?We are preparing a firmware update. Hopefully it will fix the 384KHz play back issue for everyone.

If it's the issue with COAX or TOSLINK and CD player, sorry no.Hello John, may this Firmware Update also solve the music interruption issue which some (including me) reported?
Thank you! BR, Christian
From what I gather from the JDS Atom DAC and its UAC1 firmware, once you flash UAC1 you lose the possibility to re-flash firmware, so you can't go back to UAC2 firmware. That's a bit annoying, especially when buying second-hand you might end up with such a 'permanent' UAC1 unit. I can see why not many companies support such an operation.Hi @JohnYang1997, sorry for hijacking the current conversation, but I was wondering if it would be possible to offer a firmware update to enable UAC1 mode in this DAC so that it can be used natively with the PS5/Nintendo Switch
