This is why I don't post on hi-fi forums any more. Not only is there a lot of nonsense out there, it's fiercely defended nonsense.
I once made myself quite unpopular in a discussion about jitter on digital outputs, by actually measuring it with a scope and posting the results including screen shots. Cold, hard facts don't seem to go down too well when fluff and speculation are available.
A few years ago I did build myself a DAC using nothing more than good science, proper layout technique and high quality components. Oddly enough, it sounds great - but maybe it would be better still with a silver & gold fuse connecting it to my house wiring (which, for an self-confessed audiophile I'm ashamed to admit, is only copper)?
