I think this is a fair statement. 10 out of 16 is far from conclusive, like I explained, it was difficult identifying the mod in the blind A/B test (which was extra difficult because of the 20 second delay.)

Again, I tend to agree completely what you are saying: when I just started listening to music when the Touch was modded (without analyzing SQ to death), many times I was struck by new insights, scale and drive of the music, I was sucked into the recording, more so before the mod. You describe exactly what my 'subjective' experience was. Good to see that everyone understands that I'm not trying to impose my truth or whatever: it's more of an personal journey then anything else. -- Flextreme ------------------------------------------------------------------------ Flextreme's Profile: http://forums.slimdevices.com/member.php?userid=42996 View this thread: http://forums.slimdevices.com/showthread.php?t=84742 _______________________________________________ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
