Need Some Help Choosing an Integrated Amp

Hi Folks:

My current system includes an ARC SP-16 and 150.2 amplification. I am considering moving in a different direction--going with a quality integrated amp and a separate, high quality phono stage to be fed by a new analogue rig. Right now I want to focus on replacing the ARC equipment with an integrated. I value build quality, tonal authenticity, good bottom end control and drive, PRat, and a three dimensional soundstage. Tubes are OK but I'm leaning toward solid state. Budget would be around $4k new or used. The amp will drive 97db efficient Daedalus DA-1.1's with an Esoteric X-03se as the source.

I'd like to end up with something that is as good or better than what I am using for electronics right now when running my digital front end. Any help or advice is appreciated. I've seen a few interesting products from Bryston, Ayre, Pass Labs and Sugden.
