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

RE: Non Oversampling (NOS) DAC's

Hi,

Filterless DAC's impose a predictable HF Rolloff.

It can be compensated with suitable analogue design techniques as you may observe here.

And having implemented a variety of digital filters in a recent project, including dappele-dazing and minimum-philtre (and others) I find that simple "No philtre with rolloff compensations" sounds best.

I wonder why no-one else uses it? Too cheap for the licence?

At 20 bits, you are on the verge of dynamic range covering fly-farts-at-20-feet to intolerable pain. Really, what more could we need?
