What it comes down to, in my opinion, is how any normal 16/44.1 RBCD can be transferred to a format which does the same as you described for the filtering, but now thus with the multi millions of CDs available and the thousands we like. So to me this is the only useful approach, with the knowledge that any available Hires that did not fail for any of the many reasons can be counted on two hands only and that amongst those there's maybe one I like.
Do notice that "failing" as such, for me already starts at *any* modern remaster, and all the so called Hires is amongst that to begin with. So people behind desks molesting things.
Thus : any remastered CD (just 16/44.1) already sounds way poor compared to its original counter part.
Maybe my standard is too high.
What I feel is that DSD in the end is the better format, BUT when used as upsampled means of 16/44.1 and when done right. So indeed, nothing like "only when DSD remains unmolested right from the recording" it is right. It doesn't exist anyway (when analog mixing was used Yes, but what to say ...).
So just for your information, our D/A converter is 24/768 input-capable for this filtering reason (choose any filtering means you like in-PC). Still this is not enough in my view, which is why I meantioned the 24/11.28 MHz PCM input in near future (PCM x256).
That this is also DSD x256 capable is another matter, but crucial for apples and apples comparison; now all goes through the exact same electrical means and speed and current draw etc.
What I'm also saying and "claiming" thus far (I mean, as long as the real physical thing is not operational yet) is that DSD will be the better format than PCM, when upsampled/filtered from 16/44.1. But I also said (above) "when done right". The difference ?
No noise shaping into the HF regions, no matter many will say it is harmless. So DSD as we are used to, but now without all the HF noise.
I am not saying that this will thus be better than MQA, because there's nothing to compare anyway. I mean, all what MQA will do (if all is right) is providing a lower bandwidth requiring means for Hires PCM. Remember, that Hires which does not exist in the first place.
So what this world should head for is how Redbook CD can be improved upon. At least I feel that this my job here and I think that togehther with all the helping ears (community) we do very well (in the 8-9 years spent on that by now).
Maybe this is also how I mentioned in between a few lines that most have no clue and that especially no 21 years of review etc. experience is going to help much. It is about last week's changes, and yesterday's and what pops up tomorrow. Seriously. Also, the improvements get faster and faster because we get closer and closer to the real (instrument etc.) thing and it gets more and more easy to hear the differences in objective fashion;
All we need to do is compare with the real thing, which is not much subjective ...
Hopefully this sheds a better light on my, say, bashing on MQA; it is just not the we to go forward. In my view of course, but there's some strategy behind that view.
Thank you again,
