Blowen Amp, Looking for replacement, any thoughts

This past weeked I fried the right channel on my Sumo Polaris amp. Sumo is no longer around and the mosfet transistors are also discontinued. I don't have any way of crossreferencing the parts so a repair is unlikly. If you have info please foward. So this brings me to replacing my amp. I am planing to continue using the Sumo Athena pre-amp and ADS L1290 speakers I have for a while but would like some suggestions on power amps in the 1000.00-2000.00 range. I have a friend that uses an audio research D110b. I have found one at this site and am considering that unit unless someone can give me a good reason not to. Thanks DaveL.

Don't write off the Sumo yet. A friend faced similar problems with an old Electrocompaniet. The output transistors which were bolted with two screws each on the heatsinks were no longer available. But a crafty repairman found the corresponding new transistors (albeit with smaller dimentions), drilled holes on the heatsink to screw on the new devices, and the unit is now fine.
