Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

Re: a decent paper indeed

I'm not sure about describing upsampling as a slow roll off digital filter by default. The tests on the CS8420 show that it produces significant ringing, indicating that the cut off is pretty sharp. It's stopband attenuation is around 110dB.

Also, saying that the time smear introduced by digital filtering is inaudible because speakers are worse in this respect doesn't really hold up. Speakers also produce "large" quantities of harmonic distortion, yet lesser distortion in eg. an amplifier is surely audible too.

I don't want to sound too negative though - ultrasonic noise/signal could well have a psycho-acoustic effect.

As a general thought, many CD players with high levels of noise and distrtion are often reviewed as having more "life" and realism.
