My friend was using a Burmester 077 Preamplifier paired with a dCS Apex DAC.
Sorry, I didn’t receive all the files, but I asked my friend to redo the test and upload it to YouTube.
Please check the video here:
Unfortunately, the video is in Chinese. Class D record comes first, followed by the Gryphon Apex.
He used a Burmester 077 preamplifier and a dCS DAC for the test.
Thanks!
What was the ADC, and where was it connected, or how was it mic'ed?
Also, is there a copy of the original recording?

Nice, thanks for that. I do not really care which pipeline was used, as long as the pipeline was the same for both scenarios.
However, it would be nice to know what class D amp was used, and if possible, I'd like to see the innards.
I've done some preliminary listening, and I can tell the differences are again quite obvious.

I'd love to be able to compare them using the HQPlayerPro... but that's a no-go because the HQPlayer won't open (can't decode) m4a files... bummer.
All files seem to be compressed a fair bit.... maybe capture them as wav files and upload to Cloud, then share a download link with us..??
On a quick listen, I can tell that I don't like (at all...) how 5-A sounds compared to 5-B....

I listened to the first two files posted. They both sound wrong. There is sort of etched HF edge on the sound of vocals that is unlikely to be on a good recording. Could be an artifact of a tube preamp though. Some high end dacs have that quirk too.
Without knowing what is going into the inputs of the power amps versus what is coming out, I find such comparison recordings useless. Yes, the recordings sound clearly different, but neither one sounds right. So what am I to conclude, is it that there are two problematic amplifiers? Or, maybe its that the ADC and or the rest of the recording setup is bad? There is no way to tell without some more recordings. There should be the original recording, a recording of what is coming out of the preamp, and a recording of what is coming out of each power amp. All recordings need to be uncompressed wav files.

@Extreme_Boky @Markw4 Thank you for your suggestions . This test was purely a subjective evaluation, and I hadn't considered using software for further analysis. My friend conducted a comparison using existing equipment at home, but he didn't record WAV files. If there's another opportunity in the future, I will try my best to do so.
