parasound versus bryston4bsst or krell

i am in the process of buying a amp to use with multiple ceilings speakers via a speaker split box from audioplex
For ceiling speakers, the above amps may be overkill for the application. Any one of them will be more than enough. You may also want to consider going with something like an Emotiva UPA-700 or UPA-500. That should work just as well and save you a lot of money.
