[sdiy] Digital audio demo on Youtube

[MTG]

I don't think this guy does any favours at 8:00 when he says that 
Wikipedia is confusing, "the stair-steps aren't really there". All the 
(non-1-bit) dacs I see in these old synths generate pretty visible stair 
steps... plus I'm sure there are lots of "control" dacs on the planet so 
we shouldn't just assume every DAC is on a PC motherboard (for instance).
