Upsample in a DAC or in MC?

<< < (2/3) > >>

Hi

yes, if there is a good DAC (all good impelemtations of oen of the four leading DAC Chip producers), you will not hear a difference.
I made some blind-tests with several "HighEnd listeners" and even with a mediocre DAC people could not tell a difference between the original and the DA-AD converted file.

I do not believe in multibit DAC as better, they are clearly lower quality today. Sigma-Delta is the leading edge, no doubt. Superb performance if hardware is done as the eval board.
DAC are so high quality at a relative low price its not worth to think to much about. May be the most important thing is to have good sound and no opertating system issues is using ASIO (in PC). If the DAC does have ASIO drivers, its okay.

Oversampling, downsampling is nice for some trials or if the source material does not match the DAC. In modern DAC you can't expect a sound improvement by upsampling.
I would like to try just what a difference minimumphase filters versus linearphase filter make. However it can be done in a different way (offline with SOX), just a bit more circumstances.

That's a bold statement.  Schiit DACs don't use old multi-bit chips.  They use modern technology that's not Delta Sigma.

Brian, the current state of the world is that people with very limited understanding and information, believe they know something.  The Internet gives them a whole group of people with similar misunderstanding to say "we are right".

One of the Schiit designers uses the saying "In my system.  With my recordings.  And I have not heard everything out there".

In contrast, the people whose ego leads them to believe their reading of articles with simplifications of digital technology means that they understand, are the ones saying "this sort of thing cannot sound better than that sort of thing".

BillT:
Of course, there's another view on this. The ear has very limited abilities, the brain has an amazing susceptibility to suggestion.

It is very difficult to run valid comparison test, it's very easy to run invalid ones.

Occam's razor would suggest that electronics have developed well past the ability of the human ear to detect differences but suggestibility is still alive and well.

Hi

Schiit specifies in which product they use what chip.
Each type of DAC uses a different chip, some modern, some older designs.
The akm-chip they use is most probably a Sigma-Delta (32Bit). The others are Ladder (14, 16, 20Bit), some EOL (not for new designs according to chip manufacturer).
See on their website for details.
