[sdiy] Wikipedia DCO article

[cheater cheater]

Note that most DACs nowadays are DSD followed by an integrator.
This means most NCO's turn out to be stream synths which means they
are just a whole lot of logic followed by a  classical DCO,
technically speaking.
I'm saying this because I class stream synths as DCO's. Is this right?
