Very good points. I don't think the debate is about the veracity of the source information (like you've said, in digital world, a copy is 100% identical to the original). So this copy can be tossed over and bounced back-and-forth through countless channels till the cows come home, still in the end it remains 100% faithful to its original. Where the differences may arise is at the point where a digital copy gets RENDERED as an analog artifact. Two identical jpeg files WILL look strikingly (and sometimes shockingly) different on two differently calibrated monitors. That fact is very easy to demonstrate. Same applies to the rendition of the digitized music files. Differently calibrated players will render the same and identical digital file differently. Also easy to demonstrate to anyone with reasonably reliable hearing skills. ------------------------------------------------------------------------ heisenberg's Profile: http://forums.slimdevices.com/member.php?userid=59622 View this thread: http://forums.slimdevices.com/showthread.php?t=98249 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
