I have had integrated amps, separates w/phono amps and separates w/built-in phono boards. It really is the amp quality, your personal listening preferences, type of music you like, etc. I don't think it is any one type of amp over another.
I have found that the quality of the amps involved are the greatest source of sound quality. However, having said that they must be able to sync together to produce the sound that you want.
