The self interview by Andreas is set out and 'question' and 'answer'. It is set out as fact, as though his replies to himself is actual proven fact. I can spot holes and I am not a tech in this at all. For example, he is claiming many studios has recorded at 44.1 or have created master at 44.1 for CD release, and those are then used for high resolution releases. I am saying, how does hoe know the extent of that claim? He has a few known instances, no idea how widespread that is. I am saying, if all studios have a master tape, or more recently a digital master post studio performance, surely HD Tracks or MQA would in the first instance make an effort to use that copy.
And as Warner has signed, I would suggest they would put some effort to allow that access to the higher quality / resolution original. IUf not, they are shooting themselves in the foot and the whole project is dead in the water.
I have heard some MQA on Tital is is better than the Redbook version on Tidal or my local drive, and some that are no better. Non so far that are worse, though I am still testing / searching tracks. So there is something going on IMO that is right with MQA.
The other thing Andreas says is, why bother with MQA as we already have enough bandwidth? Well, I would say bandwidth costs money for the supplier (Tidal) and there user (Client). And the delay or potential hang-ups in the data (music stops) will be more of a problem if you get close to the average 10 meg limit (as he states is average). And of course, in the real world, in a house setting the rest of the family may use the enter net at the same time, or the person listing will maybe reading the news online.
So, I think Andreas argument is weak, too late (as already posted above) and IMO hr is rattled by his dev and investment in traditional high resolution formats.
Better to button up and suit up, get on with it and accept it.
The success of MQA is going to be dependant on the exposure level (Tidal signups a large part) and MQA compliant DACs. The failure of previous HD formats was lack of exposure and lack of mainstream DACs that could play those formats.
Having said that, if MQA gives folk a sound quality boost in non compliant DACs as well, which it appears to do IMO, that will help to keep the snowball rolling...
