You might want to try a Bryston 5 channel 9STT. It sounds very good and has a 20 year warrenty. If you loose a channel all you do is remove the amp mod that's a problem and send it back, you still have 4 amps so you can still enjoy your system while you wait for the other to return.
I used 1 when I had 2 seperate systems, 1 for 2 channel music and 1 for movies.
