Need more power, Bi-amping does it work or does it just sound wrong


I am wanting to pull some amps and speakers from storage and put a system together for another room. I have a PS Audio HCA-2 amp 150 watts, PCA-2 preamp with HCPS preamp power supply and LSA Statement towers 2.5 way with ribbon tweeter 87 db 6 ohm. I use to run the LSA’s with a 200 watt high current doubling watts amp with good results. The HCA-2 claims 150 watts but I’m not sure how true that is.

 It’s sounds nice but I would like more authority and drive. So I was going to find/buy another HCA-2 but my current HCA-2 has been modified by Audio Reference Mods, over $1000 in mods 10 or so years ago, does that matter?
I’m guessing one amp would drive the mid and tweeter and other amp the bass drivers. Wouldn’t one amp drawing more watts and through everything off? With one amp modded and the other being standard would that matter?  Would I be better off selling the amp and buying a more powerful amp, only problem it may be more trouble than I want to deal with and cost more than I want to spend.

If I did buy a brute amp instead of a matching amp to run the low end and choose horizontal biamping how would you put a passive volume control on the amp, I’ve never seen that done? I did modify the crossover with better caps, inductors and resistors and the crossover is outboard for easy access. Could I just add different resistors in the crossover to the low end till I get the out put right or is that a crazy statement?
