This album with Diana Krall i think has a reference soudquality:

MQA: https://tidal.com/album/77644037

FLAC: https://tidal.com/album/73364268

I prefer the sound from MQA but it is not very easy to hear the difference in my setup.

I think the soundquality with XX 2.09, NOS1 and new settings is best ever

Thanks Peter, the winter is not so long with this SQ  Happy

I've tried listening to MQA albums, and so far still not sure about how to evaluate, or optimize settings.  I listened to both the 16/44 and MQA version of The Eagles "The Eagles"; Witchy Woman, etc.  With the same settings (my signature), I find the 16/44 version fuller, more dynamic, and engaging.  The MQA files show as 24/48, but since there is no information on the original recording it's hard to tell what original resolution is being used for the MQA version.  Will keep experimenting.

Hey Ramesh,

We must think a bit differebtly here; the original resolution will interest you a hoot, in this (Eagles) case because back at the times I was 15 ... what resolution. Right ?
What counts for everyone beginning with this is whether you have the decoding working, and you have not. See the screenshot below;

In the top right you see your "Witchy Woman" album. It is labelled "192" which means that in decoded fashion you will (in software) receive it as 24/96. Not more, because software only "unfolds" one time, and this is to 24/96. This is good because we don't want more. So we do NOT want the indicated 192 as it is us ourselves making it (even) 768. So in goes 96, out goes 768.
Now compare with the Ed Sheeran album (Divide) and see it labelled "44". *This* one will be received as 24/44.1 and there is no first unfold. But you should also not use these to test whether your decoding works. So for that use "88"'s the least and they should output 88 (or 96 when 96 based).

I am sure this is not easy to bring across as it also involves a "malfunctioning" PC on your side. Upgrade it to 2.09 or otherwise you can't see any of this. AND :
If you did and these labels do not show, then something else is amiss which could be harder to solve. But first things first ...
Btw, after upgrading to 2.09, ditch the old "Preps" from your TT (and further) folder. Otherwise their status could be fixed and you don't want that.

Regards,
Peter

PS: Coincidentally all of the Eagles albums were my first MQA's which I unconditionally liked over the normal Redbook versions. So all you need to do is somehow agree with me. And when you do, you're set. Haha.

One more new-ish hint : Select 8x Sampling Rate in XXHighEnd and the High Custom filter for 352800.

For me, this setting takes redbook past MQA!
