If I get chance I'll get my scope out and have a look at the sine wave. As for "not within a million miles" - that's twaddle! Even if the "17 bits" is correct, those last 3 bits are pretty much inaudible under normal conditions. And remember that redbook CD only has 15.5 bits anyway... You MIGHT be able to hear a difference on HDCD rendered into 20-bit or on 24-bit material...but it will be very very tiny A tiny amount of "noise" on the analogue output will have no bearing on the digital output. But I can't say any more until I see this noise for myself. By the way, the SB3 has a "noisy" analogue output, but it turned out the noise was: 1) very low level 2) very high frequency -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
