I'm going to fly in the face of convention and suggest that you listen to an amp that is not on your list: the Atoll IN 100 (or the IN 200 if you need more power).
It's a very simple unit w/ a remote. Provides a wonderfully detailed and sweet sound with the right speakers. No XLR input, but do you really need that? I have not found that XLR adds anything (nor detracts, to be fair) to the equation unless you have very long cable runs.
The Simaudio i7 would also be a great choice, albeit much more expensive.
