Hi Mnyb. Yeah, it's hard to get a sense of what the limit of the ADC is but I agree that the Transporter XLR is hitting the limits already... In comparison to Stereophile's AP measurements, I suspect I'm maybe missing the bottom most 3-4dB of what the Transporter is capable of. As for the E-MU 0404USB, here are a few numbers in RCA loopback mode - not bad as a DAC itself! Compared with Transporter XLR: 14503 The jitter is really good for the E-MU also: 14500 With digital silence playing, here's what the noise floor looks like: 14501 Noise floor zoomed into 0-100Hz range - notice essentially no 60Hz pollution: 14502 For such an inexpensive unit, I'm impressed! As I said before, doing these tests have been quite educational and will certainly let me objectively compare performance of every line-level device including cable changes I add to my system in the future. IMO this is invaluable and way better than listening to "audiophile reviewers". BTW: When Sean Adams said AES/EBU was inferior to SPDIF, was this in reference to the standard in general or specifically to the Transporter's implementation? Wondering why this would be given clearly the balanced cable's superior noise rejection ability; at worse I would have thought they'd be equivalent. +-------------------------------------------------------------------+ |Filename: 0404USB_Summary.png | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=14503| +-------------------------------------------------------------------+ ------------------------------------------------------------------------ Archimago's Profile: http://forums.slimdevices.com/member.php?userid=2207 View this thread: http://forums.slimdevices.com/showthread.php?t=97950 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
