I had a friend that did the very same thing with a 332 and 335 Levinson amps. The 332 and 335 are a little closer in power than what you are doing. 200 watts and 250 watts. He had the 335 on the base and the 332 on the mids and highs. It did sound good. Both where on their own 20 amp dedicated power line. The speakers where B@W Matrix 800 speakers.
Sad to say he end up divorced and the wife took the 332 amp in her part of the settlement.
