Rmihai,
My first choice of that selection would be the Odyssey Stratos. It is a very refined amp and more powerful than it's rating would have you believe. I had the traveling 1801's for 6 weeks last year and the Stratos was a perfect match. This was the Extreme version, however. The Omegastar is an amp that I also considered but having had a Hafler for years, I always felt that mosfet outputs, also used by Van Alstine, left a veil around the top end. After using the Stratos, which employs bipolar outputs, my experience was that the presentation and detail retrieval was there in a way it had not been before. Obviously, not all mosfet designs are the same, just my .02 worth. A used Stratos sells for about $850. Save yourself the long break in period. These amps are built to last. Good luck with your quest.
