Headphones and phase inversion. If you're using an otl type 'phone amp, like the Singlepower, (which I think I've seen you discuss on one of the headphone forums) chances are it already inverts phase. Most of the 3 tube designs do, but no one tells you it does invert the absolute. So with any of my little dacs you would net out, normal phase. Given that recordings are quite random in phase anyway, the point might possibly be moot. If you have a fairly high input Z (10k or above) on your phoneamp any of the dacs will work. The levels are now close to the 2V ref, being about 1db down. I do answer emails, just might take a couple days.
