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

Seems like all your favourites were R2R Ladder dacs, and rightly so, as Redbook (PCM) is converted "bit perfect" by R2R dacs.
Delta Sigma while good at doing SACD or DSD can only give a facsimile of RedBook (PCM).

Sorry Phill, this is 180’ out, but also half right with the "poorly" statement.
The original first issue non remastered cd's and lp’s are the best, and most important least compressed.

Do your homework here on this site and compare.

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."

To me DSD sucks, just SACD without the copyright.

Give me good uncompressed PCM (Redbook, DXD or DVD-A) converted with a well implemented Multibit dac with a well thought out I/V stage.

I think this post hits the mark better, might as well just flip a coin. 

Far too little, A little too late.

A 4 out of 7 hit rate, by a pro golden ear even

DSD vs. PCM vs. MQA - Group "listening" experiment

"Listening" is the word that should ring a bell???
Look at the title, "DSD vs. PCM vs. MQA" it can't be done fairly without compromises using the same dac.
Maybe it's you that needs knowledge or professional help, as one of your statements suggests, "The ripped cd file sounds better than the cd spinning in the super heavy transport of my old Esoteric K-01."  

Cheers George


jon when are you going to stop trying to be a forum cop??

The OP asks in his title
" DSD vs. PCM vs. MQA  Group listening experiment "

I say it can be done with any validity because one dac can't do all at their best!!!
So it can't be a valid comparison.

If that's the case, then the PCM for it to sound it's best should only be listened to via a dac that is Multibit conversion.
Not one that is a DSD dac with/or Delta Sigma, Bitstream, Single Bit, Saber, or Wolfson sd DAC convertors.

From MoJo Music: and others have said the same.
" When a PCM file is played on a DSD or Bit Stream converter, the DAC chip has to convert the PCM to DSD in real time. This is one of the major reasons people claim DSD sounds better than PCM, when in fact, it is just that the chip in most modern single-bit DACs do a poor job of decoding PCM."

Cheers George
BTW here are a users findings of the Schiit dacs with Multibit upgrades doing pcm conversions.
https://forum.audiogon.com/discussions/difference-between-schiit-modi-versions

So saying that it's really impossible to compare DSD, and PCM as they both need different dacs to get their best. 

Cheers George


Fery few multi-bit dac's left really.
  Not really they are more than ever now, as in the hi-end they're realizing now that to do PCM conversion right it has to be done with Multibit.
Hi-End ones like MSB's flagships, Total Dac, Metrum, Schiit (has upgrades to multibit) Aquahifi and many many more.
Here is the latest from Aqua.

Does anyone know what type of dac was used to compare these group listening experiments with??
