I don't have any experience with the equipment you mention, but two years ago I switched from separate Pass phono preamp, preamp and power amp to a Jeff Rowland Concentra I w/ phono. The sound was clearly different, but only slightly so in musically significant terms and I've never felt the Rowland was a step down in performance.
The current issue of The Absolute Sound has an article where different reviewers assemble complete systems. Of the nine systems, five were based upon integreted amps. Great systems can be based around integreted amps. Give it a try, you might be pleasantly surprised.
