It would also may be easier to fit a multi-channel amp in the AV rack?
Do you think the 200w x 5 would be insufficient for the fronts?
A well built 5 channel amp like Anthem MCA 525 or the one you're considering will easily drive your base layer. A good as amp isn't just about power, a good amp will help get the most out of your speakers. Also the Reference 1's (as are all Kef bookshelves) aren't super efficient so even a $12000 amp will not help you achieve rock concert levels. What You'll get is good dynamics and great sound out of those fantastic speakers. You have very capable speakers that can play well below 60hz and those rhythmik subs are very articulate and great for music. I'd experiment between a 60-80hz crossover.
