I simply don't buy Trinity's claims about the shape of a 10 kHz sine wave signal at 48 kHz sampling rate on their Trinity DAC website:

It seems to be pretty well debunked by this website:

and the video:

The video appears credible since he uses defined equipment on which his experiments should be easily reproducible -- his demonstration is convincing.
(I was alerted to the education website and video by other WBF members on another thread --thanks.)
