Headphoneus Supremus
I've found the M-DAC's amp decently capable but it does seem to work better with some phones. I quite liked it with the LCD-2's but prefer the W3000's out of my vintage Harman Kardon receiver. It's funny, I would have expected the opposite. That said, in general terms I think the internal headamp does a decent job, there's definitely going to be better standalone amps, I think that's a given, but it works well as a stepping stone or in a secondary situation.
