Title: DAC in Apple Lightning to 30-pin Dock adapter
Post by: Sebastian Mares on 2013-02-15 10:10:04
Does anyone know which DAC Apple uses in their Lightning to 30-pin Dock connector? Any idea if the cheap China copies have different, lower quality DACs?

Actual pricing on Wolfson DACs is hard to find, but competitive DACs from well known producers run about $1.50.

Fine performance, no surprises, no audible coloration.
