不同Analog-to-Digital Converters 製造出來的DSD files 的音效分別

CKKeung

有興趣試試不同的 ADC 製造出來的 DSD files 的音效分別嗎？

Bruce A. Brown 是知名的mastering engineer，近期的 Wilson Audio 發售的 high resolution music files 就是由他所操刀的。
http://www.hi-av.net/modules/newbb/viewtopic.php?topic_id=1541

他有5部不同的 Analog-to-Digital Converters，用作把 Wilson Audio 以往的 analog master tape 經過 studio內的 modified Studer A80RC MkII 和 Doshi tape pre 送到它們後，轉化作 high resolution PCM or DSD files 出售：
1. Modified Korg MR2000s BLK
2. Modified EMM Labs ADC8 IV
3. Ayre QA-9 and Mytek Stereo 192/DSD DAC
4. Merging Technologies Horus
5. Grimm AD1


Bruce 把同一個 analog master tape 音樂段落 用以上的5部ADC製作了5個DSD files，發覺它們的音效是不同的！

大家有興趣試試嗎？  幾好玩ga！  

多謝收看，請各位師兄給小弟加點分好嗎？  謝謝！

CK hing,

it is a great finding can compare the performance between DSD128x and DSD64x for each files and compare each ADC files.   

which ADC converted files you feel will sound nice?  Hope I have chance to listen to them in the studio today.

Cheers!

CK hing,

We can compare the performance between DSD128x and DSD64x for each files.   

Bruce will reveal the identities on Sunday (USA time).

A tip : Bruce's personal favourite is Grimm.

hope I can listen to them, both 64x and 128x versions before he disclose the result!  

do you think there will be different result (or ranking) with different DACs?

cheers!

do you think ...

This is an interesting question!

Theorectically and from an engineer's viewpoint : the files should be identical so the sound shall be the same.

There had been both overseas & HK mastering engineers doing CD ripping to PCM with different ripping softwares.  Apply checking softwares to these files could not identify any data difference but some audiophiles swear by that sonic difference on playback exists.
I am sure if engineers apply checksum softwares to these DSD files, the report will be that they are identical.

However, Bruce's DSD files do sound different.
I am asking him whether there could be some confounding factors.
For example : Was the Grimm CC1 clock used with Grimm AD1 which was his favourite?

No problem logging in. Remember the !.

I have heard 3 out of the 5 brands DAC/recorder before.

My ranking is as follows from best to worst
DSD128 002
DSD128 003
DSD64 003
SD64 002
DSD128 001
DSD64 005
DSD64 004
DSD64 001

Actually it is not difficult to know which files(DSD128 and DSD64) are from the same AD machine.

Thanks CK for the links

CKK 兄，
Thanks a lot for the link.
.
On the other hand, I do think that these file should sound different.
The analog sound needs to go thru the AD's analog stage (amplifier) and then convert to the digital (with different algorithum for different AD ?). These two things together would make the output (digital file) different .
.
Thanks again, it is fun to carry out blind testing.
Cheers.

Would the result be superior if say the recording and playback machine is of same brand?  E.g. EMMLabs ADC with EMMLabs DAC, also Ayre QA9 with Ayre QB9 etc...

試咗，聲音我prefer #2 同 #5, 分隔度、像真度、人聲收貸。
其如#1, #3, #4全部人聲晤合格

我部dac只support dsd64

This is Bruce's preference :

" I would say it's a toss up between the Grimm and Horus.  I like the Grimm better at 64fs and the Horus at 128fs.  
Most people pick the EMM/Meitner because it has a great coloration. It's not accurate, but it does sound good. For my listening enjoyment, I'd pick the Meitner.
For mastering and knowing I depend on what goes in, comes out, would be the Horus. The Grimm is somewhere in between. "

Many overseas CAS audiophiles choose 002 which is EMM Labs ADC8 IV.

This is also the choice of Wi ...

因為錄音太短及單調，好難單憑咁就定高低，只能講有啲ad比較啱呢類人聲近咪錄音

我只聽到人聲好像是 Bad Company 那個
