DSD vs. PCM vs. MQA - Group listening experiment

Hi everyone,

So I just re-discovered the 2L website which has free samples of high resolution music.

I thought it would be worthwhile to ask the fans about the tracks here, specifically if there are any you feel are really good exemplars of why encoding scheme X is better or different than Y.

I just downloaded a bunch of Vivaldi and will share my own observations (and lack thereof) here.

As for me, file size matters so I'm going to try to stick to relatively similar file sizes when possible.

Best,


Erik

@rgs92 do you mean to say you are able to hear a difference in a BLIND test between PCM and DSD? If yes, that has never been known to have been achieved, nor is that documented by an applicable and recognized scientific study.

@gdhal You are right, but I personally seem to slightly like DSD better so far. No idea why.  not sure I'd pay for the extra hard disk space for it yet.

What I do know is that I've never heard a difference between PCM and MQA encoded PCM.

From "Real HD Audio" 
"DXD is the recommended recording format “when setting up systems for the absolute highest sound quality”. It turns out that DSD AD conversion is just not up to the task because of the lack of tools and the high noise levels that are generated.
So what the Sony and Phillips folks are actually saying is that HD PCM at 352.8 or 384 kHz and 24 or 32-bit word is the “best” system for capturing audio."
Cheers George

I could be absolutely blind. Any glare that is in vocals from PCM that keeps me from turning it up is GONE. The bass is solid as a rock, much more solid  than PCM. I have many things that are unlistenable in the first 5 seconds on PCM that are fine and wonderful on SACD. SACD makes all the difference. That's why I buy these discs whenever something I like is released. This has been since 1999 and the players have gotten even better.
Cheers also.
