CV, how would that be cutting corners if that's exactly how a lot of modern source material is converted before mastering to CD? Master tapes are usually of higher resolution than the CD format can handle.
Note the bold. No matter if it's theoretically a perfect representation, it's not a CD, and there can always be arguments made (admittedly weak) that it's not showing the sum of differences between formats. To eliminate all doubts is to have actual SACDs and DVD-As versus actual CDs. Otherwise, it's cutting corners, or are we just not as anal about such details as the tweak faithful?
