I have had Burson Soloist w/ the warmer of the 2 dacs offered.
I found it a bit bright w/ LCD-X
Used the McIntosh MHA100, and it was great, but more expensive
than I felt was a great value, so I sold it and broke even.
I now use the Bryston BHA1 with a Bryston BDA2 and it is a great great match for the LCD-Xs and I'm sure would be also for the Sennheisers...
I've heard good things about the Ayre Codex.
If you don't need a built in DAC, you might look at Wells Audio's headphone amps......have heard them at RMAF and they are probably the ones to beat overall in my opinion.........if you go tubes, I'd go Decware Taboo
