Thanks for the responses fellas. I did some checking on this Wolfson receiver and found an interesting post by the guy who designed the Neko DAC.
http://www.nekoaudio.com/forum/viewtopic.php?f=4&t=23 "But I decided to not worry about jitter at all by choosing the Wolfson WM8804 S/PDIF receiver. Wolfson designed a chip that would not carry input jitter through to output jitter. So as long as the input signal is readable, you get a nice stable output signal. For more details, check out the white papers listed on the WM8804 product page. Now, irrespective of all this you still want a relatively clean transport. After all, if your transport's digital output stage isn't reliable then there's not much a DAC can do. I've come across computer sound cards that were improperly grounded inside or included noise in the MHz bands on its coaxial output." "The WM8804 is driven by a 12MHz oscillator. The incoming S/PDIF signal is locked onto using a digital PLL. This data is then placed into a buffer. The 12MHz oscillator is used to generate a clock, and values are pulled out of the buffer as needed. So now you have a data value synchronized with the internal clock, and the internal clock is clean and steady as it is derived from the 12MHz oscillator. There's a little more to it than that, which you can read in the white papers, but by rebuffering and using a good internal clock, you get a clean and steady audio stream. In fact, one use of the WM8804 is simply to reclock an incoming S/PDIF signal and output a "cleaned up" S/PDIF signal." -- Kellen ------------------------------------------------------------------------ Kellen's Profile: http://forums.slimdevices.com/member.php?userid=16569 View this thread: http://forums.slimdevices.com/showthread.php?t=73882 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
