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.

You don't even have them in your room yet, so you don't even know how they will perform.

I'm surprised getting them setup in their best location first isn't mentioned.
I hope you can get them out in the room, along with appropriate room consderations. THEN, consider all those other suggestions.

I've heard them perform fine with modest tube amps. Add subs...WOW!
