Dear Peter,
thank you for sharing your experience and opinion.
I completly agree with you!
For sure it is not as intended to "sound" a certain track into a specific direction. When the recording is not so good then also the playback should give you an idea accordingly about that.
I really have the same approach to test the different settings but I am more looking on the focus of voices and staging in general (width and depth).
And what you mentioned before, the commercial use to demonstrate a system:
Here you want to really perform each track at the utmost possible performance, which might be a little different from track to track.
Something which we have to consider in my situation is that the Trinity DAC can work at 176,4 or 192 without any digital filtering (see www.gte-audio.com).
This is a major difference to the other DACs I know.
One option which would be really convenient for me (maybe only me) is as follows:
If I have playlist with contain 44/16 and 192/24 files, it would be nice to define Quad and Arc Predition for 44/16 and no upsampling on 192/24.
But I have to really congretulate you. The sound quality is so awesome now with quad and arc prediction that I am really stunned.
Best regards
Rainer
