Bryston 4B SST-squared vs Classe CA-2200

I currently have the Bryston 4B SST-squared. They are paired with Von Schweikert VR4-SR Mk3. I enjoy the Bryston's authority and slam but am thinking there may be some top end refinement missing. The VSAs are *very*. I have to opportunity to get the Classe at a decent price and am wondering if this would be a worthwhile upgrade or more of a parallel. I know that it will be a slight step down in power with the Classe but am hoping that their overall balance will work well with the VSAs. Music is a mix of rock and jazz.

Unfortunately there is no local Classe dealer at my location so if anybody has been able to do an A-B comparison I would greatly appreciate your input.

Thanks!
