What about adding USB digital audio to your SoundLab project? Shocked

cebec should check out the info on page 7 comparing DACs and out of band noise. We spent some time looking at this on the G2 IIRC.

Yeah, that's it!

And I'm sure one of the Competitors is a Crystal DAC. I've since seen these out of band noise profiles on the G2 and a Machinedrum (which also uses Crystal DACs). The amplitude of the out of band noise is MUCH greater on the latter, though.

Page 7 of the AKM guide doesn't go into any further detail on 'EMI' or 'Amp instability'. I'm also wondering if a signal reconstructed with, e.g., a CS4392 at 96 kHz with out of band noise starting at 31 kHz at -132 dB and peaking at a little over sf/2 and ~-120 dB will a) make anything more than negligible impact on the rest of the signal chain, and b) if sampled at 96 kHz be attenuated even further at the ADC, or at 48 kHz attenuated completely, etc.

Thanks for the tip, jk, and for the links, Stein.
