Marco - Now I understand what you mean by systemic... So, yes unless you lock the clocks when recording the results will not be "systemic". Also, each time you play something back it will be very slightly different... ...and yes, it is possible for external factors to affect the clock. However, changing the plug-in power supply does not do this (I've tested this to death). I haven't tested vibration. The FF/REW issue is nothing to do with this - that is just a functional coding matter, it has no impact on the sound. As I said, there is no measurable evidence to support the idea that flac vs wav playback are ANY different. To me they absolutely sound identical too. If you can afford it, I would look into the Touch when it is available. It sounds (and measures) better than the SB3. It may outperform the SB+. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
