Conrad Johnson had always gone well with Vandersteen , especially the tube equipment. I have not heard the Ayre with Vandersteen , but have heard many good things with the pairing of the two.
I would contact John at Audio Connection in Verona ,NJ. He is man to talk to about Vandersteen products. He sells both Ayre and Vandersteen. He would be able to give you a wealth of knowledge on this subject.
