Accuphase preamps

My research tells me that their preamps have some of the most features of solid state designs. Also, I have heard them @ CES, they sound very good indeed.

My question is, will they mate up ok with other brands of amps.

Right now I have Bryston amps, and a BP6P preamp, and I'm not too crazy about getting a BP26 because of lack of features.

It also appears that Accuphase is the better design as well. Am I wrong?

Thanks.
