Although I believe that amplification is almost always the weakest link in most any system, I'd have to guess that in your case, the B&K Ref30 is perhaps the weakest link.
I say that only because I've read several reviews in the past few years on the Ref 30 and the reviewers seemed to consistantly state that the ergonomics are nice but the sonics are mediocre at best.
Therefore, I'd lean toward replacing the pre/pro. But for that I would elsewhere than what you have mentioned. Have you ever heard of Primare? Excellent pre-pro that I've owned that I compared to some outstanding 2-channel preamps and outperformed almost everyone of them in almost every category. New the Primare retails for about $3700.
Are you looking for 7.1 or 5.1? What other characteristics are you seeking for a pre/pro?
After the prepro, I would then look at replacing the amplification.
-IMO
