The cheap little DacMagic that has been talked about all over the boards uses two of the 8740s, and I think Onkyo has incorporated that part in a lot of their products now. Probably more, they are getting pretty popular. Minimum phase designs for the masses :)
But yea, it would be nice if they offered something that had a better DAC stage along with current outputs instead of having to use the switched capacitor/opamp type voltage outputs. Nothing better than a ladder and simple current mirror in my experience for I/V conversion with PCM sources. Or even if they could just offer the digital filter outputs so one could use their own preferred DAC stage, that would be nice too, and would probably sound pretty good hooked to a PCM1704 or something like that.
