Last night was I thinking (I know I shouldn't think because it only causes trouble) about the above jitter measurements and I was wondering what, if any, jitter is present when streaming audio, either via WiFi or Ethernet, and using the Touch's or the Transporter's internal DAC? And if jitter is the big, bad bogey man that the audiophile world is presently all a-jitter about then why isn't the streaming method of transmitting digital audio data to a DAC, as used in the Squeezebox devices and the Linn DS series (I believe), being adapted as the state of the art standard and not the asynchronous USB interface? I still maintain that the current anti-jitter craze stems from the lousy jitter characteristics of the standard USB 2.0 interface when used to transmit digital audio data and has now been expanded to encompass other methods of digital audio transmission, e.g. SPDIF, Toslink, etc., which in the past were never considered to be problematic with respect to jitter. ------------------------------------------------------------------------ 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 audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
