Hi Pummill,
I tested the new Rotel 1077, that class D amplifier, 4 days ago on my 3.6R. I'm bi-amplifying the maggies with a Marchand electronic xover. I have used 4 of the 7 amplifiers available into the Rotel. It was very good. Not as good as my actual amplifiers, but the Rotel is twice cheaper than my 2 amplifiers!
If you like the Rotel sound, you may like this one. It also helps to access bi-amp which represents a huge improvement on the maggies!
Or you could go for a second 1090 ;-)
