Great ! It also seams like Wifi has a bit higher distortion a whooping 0.0002 % more :) atrocious . So the FLAC/WAV thing is also an Nigerian letter to the audiophiles . You can say that flac is "better" on a Touch but that would be silly with the very small differences . The most interesting thing is that the ones claiming that they hear this difference often uses external DAC's too ? ------------------------------------------------------------------------ Mnyb's Profile: http://forums.slimdevices.com/member.php?userid=4143 View this thread: http://forums.slimdevices.com/showthread.php?t=97950 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
