My 21 year old son is graduating from a business college this spring. He is very in to HT/audio. He has a Yamaha rxv-496 receiver, PSB 5t's as mains, a PSB sub he is very happy with, some small BA surrounds and a rat shack optimus center channel. I would like to help him upgrade his set up. Should I do something about the receiver, such as add am amp, if possible. Or add a matching PSB center channel? Would it be bad timberwise to mix in an axiom center channel into this conglomeration? He would like to keep the 5t's as his mains.

I have been contemplating the m60's as mains and the vp150 center. But, he seems to be happy with his PSB's.
