Audiophile digital audio flow chart/time line: Middle aged audiophile would like to get in on the computer based audio revolution and being an audiophile he only buys the best so therefore the computer he owns is a Mac, since Macs are the best computers. From here it all goes downhill. Macs do not play flac files so only wav files will do and since Macs are the best computers wav files MUST be better than flac files. Articles are published in the lapdog audio press stating that flac files do indeed sound inferior to wav files. No real proof of this assertion is provided. The most common way to play digital audio files from a Mac is by using the USB connection. Please note that audiophiles do not consider Squeezeboxes to be "real" audio components since although these devices are well reviewed by the audio press all the reviewers clearly state that they only use these devices to stream low fidelity internet audio for background listening and never use these devices for serious listening or as a basis for comparison to disc based players. Jitter tests clearly show that normal USB connections, even from Macs, are filled with lots of very evil jitter so the asynchronous USB craze is launched which in turn leads to the overall anti-jitter craze. Please note that the anti-jitter crusade is based on measurements and the statements of a few golden eared audio gurus who claim to clearly hear the effects of jitter, something that audio science tells us is impossible for normal humans. So in summary: my SPDIF connection from my SB Touch to my Headroom DAC is now filled with very nasty jitter all because audiophiles have Macs! God am I upset! ------------------------------------------------------------------------ ralphpnj's Profile: http://forums.slimdevices.com/member.php?userid=10827 View this thread: http://forums.slimdevices.com/showthread.php?t=97950 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
