that list i would choose sim without much thought, its a great sounding piece. hegel 590 is another to consider in that price range

If you have not all ready decided, with 90db speakers you can easily go with Class A. I am very pleased with my Pass Labs INT-25 and expect it to be my last amp purchase (famous last words?). Wanting to stay with a smaller 'form factor' my 2nd choice was the Bryston B-135ST-cubed. Don't hesitate to go used. High-end gear of today is very reliable. You may find a demo unit by calling around to the various shops.

The Western Electric 91E Integrated is on this month's cover of Stereophile. The review was quite positive as well.

The Rowland 1500wpc Class D 'Daemon' integrated amp at the Captial Audiofest was very, very impressive. It was one of the top systems/rooms for me with Raidho speakers. I'm thinking maybe Class D has "gotten there". For $38,800 it should sound good.
