Marco, The differences you describe do not show up in testing with AudioDiffMaker. The analogue output from both SB3 and the new Touch are identical with WAV vs Flac, as is the spdif via an external DAC. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
