In Reply to: RE: Has any company updated to MQA via firmware? posted by Isaak J. Garvey on August 25, 2016 at 07:13:52
... there will be many others requirements :
Enough room inside dac's memory to hold the supplementary firmware
Enough processing time slices available to process it
Some testing to make sure that the supplementary load does not offset dac's original performance (as far as it is alleged that the lower the DSP's load, the lesser are the perturbation it generates)
Follow Ups:
The more I read interviews with the principles, the more I am convinced it is vapor ware.
MQA could be implemented in firmware IF there's enough processing power. It's not as simple as unzipping a file. It also is not generic. The temporal correction applied is said to be unique to each DAC.
Having said that, the samples I've heard of MQA files on a Mytek Brooklyn were completely unconvincing. I have not heard any benefit whatsoever. The claims of better.... whatever it's supposed to be..... have yet to be heard in this house. To be most fair I used a pair of AKG K712.
As I've said elsewhere, I won't hunt for benefits with tweezers and a magnifying glass. If MQA isn't easy to tell, it's DOA. After listening however I think I like DSD a little better than PCM. Not sure I want to pay for the gigantic files though.
...and as far as DSD vs PCM..the format used to archive a maatertape should depend on the music itself... i am big fan of DSD, but 24/192 PCM is excellent too.
BTW I around 2000 24/192 albums and almost as many SACD rips. Believe it or not there is virtually no difference in size based on a typical 40 minute album.
It seems to me you are a pretty well informed poster.
You are 100% correct in that the algorithm must be custom implemented for each DAC, hence the requirement to send a sample unit to Meridian.
This is absolutely a solution in search of a problem. And it is disgusting that he audiophile press is lapping it up.
