And actually good hearing makes it harder ? The perceptual masking parts of the codec relies on does not work properly in some case of damaged hearing . Funny enough really badly produced music with tons of dynamic processing can actually stress the codec more , the scientist that designed these codec was thinking about " natural " music when doing it , orchestral work with a lot of ambience code well. Also , some mp3 decoders are not 100% perfect the ones you use on a computer is the bests especially if it is lame . Mathematical compromises in portable players and actually squeezeboxes ,can produce artefacts in rare cases . If you have a lot of high quality stuff in 320kBps mp3 it migth be a precaution to let the server handle it , note that I've heard this in one or two tracks over the years , so server side decoding is just to cure the "audiophilia nervosa" . Lossy codecs actually uses more CPU and math to decode than lossles codecs , and squeezeboxes do decode lossles formats bit perfect . ------------------------------------------------------------------------ Mnyb's Profile: http://forums.slimdevices.com/member.php?userid=4143 View this thread: http://forums.slimdevices.com/showthread.php?t=98591 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
