I've put this together over the past year and I'm pretty happy with it for now. I love the sound signature of the Ayre and Vandersteen, the imaging is fantastic. As I upgrade I'll probably look to just up the ladder within those brands.
the Ayre is the integrated and the MS pre is a phono pre. I have the same integrated and have Treo's purchased. Yes, the Vandy's will sing with that system.
