[sdiy] Novation peak NCOs

[Andy Drucker]

I'm trying to understand, in the NCO architecture being discussed
(tentatively as we don't have exact details from Novation), is the choice
to use a 1-bit DAC forced on us by other aspects of the design such as the
very high (96MHz) sample rate?

If not, is it a cost issue, and is it likely to be perceptibly worse (to
some ears) than alternatives?
