The 33h would have (in my opinion) plenty of juice. I own the 335,33h,and the 33. There is honestly no comparision between them.
The power supplies for the amps is what really make these amps sing. The big mono's regenarate their own 60 hertz signal. Power supply is also much bigger in the mono's. Their respective shipping weight for 2 channel is 335=150lbs,33h=440lbs,33=870lbs. Guess what, power rating of 335 is 250w @ 8, 33h is 150w @8, and 33 is 300w @ 8power. When I originally bought my 33h the audition incuded my old CJ 11, KRELL FPB 600, and PASS . In terms of bass slam the 33h had better bass control, definition and slam. My speakers were and still are the WATT PUPPY 5.1. I have owned maggies and yes they are very good with the proper juice. Please remember that the best thing is to audition them if you can. System and room interaction always play a HUGE factor in the equation.
Good luck.
