Both is possible, IMO. I assume that Mooly has already received several impressions. I have received one comment and I have forwarded it to Mooly.
Before I disclose what was tested, I will provide you with complex set of measurements of both 'blue' and 'green' chain. We shall see if it has or has not any relevance to listening impressions.

I was going to say I don't mind collating them if you want to pm me. Yes whichever 🙂
POLL IS NOW CLOSED
POLL IS NOW CLOSED
First, I would like to show the level of amplitude matching of the 2 music samples used. There were 2 audio chains:
1. blue chain: D/A - 'blue' device - A/D
2. green chain: D/A - 'green' device - A/D
D/A and A/D were same in both cases.
FFT of complete blue chain and green chain are now attached.

2. green chain: D/A - 'green' device - A/D
D/A and A/D were same in both cases.

Thanks Pavel! If you still have the setups active, can you do a sine at 5kHz, please? That often shows more difference than 1K. When you see my comments, you'll understand. If you want to do dual tones, too, we would be happy to see them.
OK, I was delaying a thing a bit. Even 5kHz makes almost no difference. Please see complete RightMark results, with IMD vs. frequency as well. I am not posting hardware setups yet, for you guys to have a space for sending your impressions to Mooly.
Anyway, I assume I can guess your comments, they might be similar to mine and might be the reason why I started this test.

Thanks Pavel. I was just curious because neither Blue nor Green sound like the rip I have of the same song. Maybe your source was different, or the master was. I suspect both, as your files are @ 48K, not 44.1K
My source was 'Studio Master' 96/24 flac file for D/A playback, but recorded at 48/24 A/D after it passes through 'blue' or 'green' device. It should not matter as the original has almost no content above 20kHz. But, the D/A - A/D process has changed the resulting sound somewhat, when I compare it with the 'Master' 94/26 in a listening comparison. So I agree with you, it sounds different from the Master data file.

Firstly, thanks to Pavel for doing such a professional job with all the presentation and so forth.
The final big reveal I believe is tomorrow morning (so around 12 hours from now) and I can't wait.... the hidden poll means there has been no influencing of votes by seeing how other are voting. You voted on listening.
And I had the very very strange idea that we are listening to an 😱 can I say now 😀

I thought.......... it might be an RIAA preamp with inverse network to bring it back to flat response 😀
There, I've said it 😀
Yes, for those just reading this the poll is CLOSED and no more votes or comments can now be accepted.
Many thanks to all of you that took the time and trouble to listen and to vote.

Oh no, it was not. I assume that RIAA - anti RIAA would make bigger difference. We would have some added noise for sure and probably changed tonality, as there is quite a huge gain in the RIAA preamp. Also, it would be very difficult to keep almost same frequency responses in both channels.
