Will this amp trick work for increasing bass performance?


I'm considering matching Focal Utopia Scala Evo with two amps for bi-amping, to separate bass and mid/high. 

I'm considering the Pass Labs XP-32 pre-amp, which has individual volume controls for each channel/amp. By slightly increasing bass amp volume over mid/high amp volume, I get to feel more punch from the 11" woofers. The crossover in the Focals cuts off at 220Hz, so only bass and sub bass are affected.

Which two power amps would you consider? Power amp budget is about $30K. Was told Focals like power, so >250W for bass amp seems the minimum. Pre amp will likely be Pass Labs XP-32.
Maybe Pass Labs X250.8 + X150.8 or X250.8 + XA60.8?

Your thoughts please? Any other ideas to get more bass performance from the 11" woofers in the Focals? Subwoofer is not an option. I know McIntosh has a pre-amp with equalizer, which would solve the problem too. But I always thought EQs are a no-no.

This is a nice problem to have. Get the XA60.8 on top and a pair of JC1+ amps on the bottom. If they are anything like the old JC1 they will have a damping factor in the thousands and plenty of power Fabulous bass. Better than any Pass amp I have heard and Pass amps are no slouch. The XA60.8 will be like heaven on top. When you get it done please invite me over.
