PelPix:
Disclaimer: the SRC is *SO BAD* that it adds 30dB of noise and 10x THD%. Resample your music to 48k before you play it or face the SRC's wrath.

OJneg:
Is that what we're seeing with the high amplitude signals? Some sort of lobe-ing?

Probably. It still looks resampled even at its native rate--it's just resampled the best.

I think this thing crunches 48k down to 48k even though it's already 48k.

The DAC itself is really good, though. If only we could get bit perfect.

Have you used the Neutron player?
