John,
I've no doubt you know more about the subject than me but I think your
language, namely the appearance of "want" and "guess" in the same
sentence, might fan prejudices about digital audio!

Do you mean DAC designers are use cheap short-cuts that aren't in fact
even trying for the correct sampling-theory ideal, but instead cheap,
expedient replacements of it? Perhaps you're suggesting your way is
actually a theoretically more correct way. I am not here arguing with
these assertions.

All I'm worried about is the wording of the above sentence, since
guessing is not something we really -want-, if we are trying to
implement sampling theory faithfully (I am sure you agree by the way!)

Regards, Darren
