You didn't mention if your principal source is a turntable or digital. If turntable, definitely make sure your phono stage is separate. I have an AB integrated with SS phono stage. I used to use the amp's phono stage and getting the separate one was a huge improvement, and supposedly the one in my integrated is excellent.
I agree with someone who said if your power requirements dictate mono blocks, get all separates, otherwise a similarly priced integrated versus separates should deliver better value all else being equal because of the cost savings of the parts and cables cut in 1/2..
