In Reply to: Femto Clock in a Streamer - why ?? posted by AbeCollins on October 27, 2015 at 14:29:22:
Well, femtoclocks are great at resolving engineering needs of low-jitter digital devices like multi-GHz CPUs, SATA interfaces, PCI Express, etc...But we're talking audio devices here with sample rates in the low MHz (DSD) and most often <192kHz in terms of timing demands of the final output.
The real question is therefore - what engineering question is the femtoclock "solution" supposed to address? What "jitter" in audio requires this resolution? What device can anyone demonstrate femtoclocks materially improving the output quality in?
Hey, I'm all for technological improvement and it's great that products are out there to be purchased for anyone who wants the tick-box checked when purchasing a SOTA DAC... But I think it's quite clear that this is unnecessary over-engineering whether in the streamer or DAC side. And logically the OP is correct in suspecting that a better clock in the DAC is more important.
