Well no matter what if you put mono extremes is about 10 times the amplifier in sound and quality... So thats a choice you need to make based on price, but it is very safe to say that you will not be going down in anyway from the Rotel. I have heard Rotel amps but not specifically this one. However the only other close peers to the Odyssey in price performance(and even way higher price to be honest) are a few McCormack designs, Belles, And Mcintosh.. With the Infinity speakers its a toss up, fact is no matter what a mcintosh will sound very nice in this combo. But odyssey you will get more for the money, mcintosh is very musical, odyssey is very Lab grade accurate, its not harsh just will sound like the components in front of it without color, the mcintosh may sound a bit more fuzzy, this was my experience anyway.
