In my system, it’s just the opposite. The ripped cd file sounds better than the cd spinning in the super heavy transport of my old Esoteric K-01. Many others in audioland have also found ripped files to sound better than cd’s.
To be fair, I have also upgraded to the new generation Esoteric N-05 dac/network player. The usb implementation in the N-05 is miles ahead of the K-01. New digital gets cheaper and better in doing wonders for redbook.
When I switch to hi-res files, the difference isn’t that dramatic.
My entire redbook collection now sounds better than ever and the good recordings sound as good as hi-res.

(Ptss, we can only hope YKWYA doesn’t come forth to tell us what I already know about the chip residing in the Esoteric N-05)
