Well - very interesting. I plugged in some Sennheiser PMX60's into the Touch and repeated the test above, comparing TinySC with phones in vs. TinySC with no phones.
The overall correlation null drops by 6dB to -80dB, meaning that with Phones connected the analogue signal via RCA out is changed. What is more, the change is mostly on the Right channel out of the Touch. The left channel is much less affected by the Phones being in-circuit (2dB). I repeated the test several times with consistent results. I would expect this small difference to be detectable by some people under the right circumstances. It will probably depend on which phones are used - I'm guessing the impedance will matter. I'll try and see what happens with Phones in and replay via sbs... -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
