However, ripping a DVD-A (using DVDAudioExplorer) avoids all the issues mentioned and produces a bit-perfect copy at whatever the native sampling rate/bit depth is on the disk.
The Benchmark paper is talking about what appears at the S/PDIF output of a normal DVD player. In the context of Squeezeboxes, this is unimportant. There is a well known paper that describes a test where a 44/16 ADC/DAC is inserted into the replay chain and no-one could detect it. The reason I am interested in ripping DVD-A's is because they often contain a superior sounding master mix to the equivalent CD. However, the same is often true of Japanese pressings of standard redbook CD's (especially the recent SHM-CD's). Having done quite a lot of side-by-side comparisons of the same track at 24/96 vs 24/48 I agree there is no perceptible difference on the Touch. However, something appears to me "better" about the Touch compared to the Classic when driving a DAC, and whatever it is is material-independent. The difference isn't huge but it is there. I was running the SB3 and Touch side by side for about 3 months (into the same DAC) and quick A/B's were not categoric, but over longer periods the Touch won me over. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
