classe cav-75 bridged into 4 ohms?

i'm planning to get some maggie 1.6's. i've used the cav-75 in normal, unbridged, 8 ohm environment and it sounded awesome. has anyone used this amp with a 4 ohm load? if this doesn't seem like its going to work...i'll guess i can sell the amp... any sugesstions for a 2-channel amp for maggie 1.6's or a pair of mono's?
thx

Thank you everyone for your thoughts. I finally broke down and called Magnepan and asked them about Joe Abrams' idea... confirmed as best option.

Does anyone have suggestions on a good pre-amp to match? Definitely need photo stage, and maybe a dsp (although might by separate HT). I think someone is (or was) selling a Classe 47.5 ...
