Assuming there is truly blind testing going on here, I'd assume the difference is the typical case created when there is even a slight volume difference in the playback of the two files. It is well documented that this preference bias can exist with even tiny volume differences.
In this particular case, do the FLAC files have replaygain info and is the SB player set to use such info in playback? If so, there certainly could be imperceptible volume differences between the FLAC and WAV files on playback, but these differences could be affecting your preferences between the two files. -- garym ------------------------------------------------------------------------ garym's Profile: http://forums.slimdevices.com/member.php?userid=17325 View this thread: http://forums.slimdevices.com/showthread.php?t=71321 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
