I am planning a home theatre. I will most likely use the M3ti's for front speakers (currently have Bose AM5's) and was considering the Axiom surrounds. I will be going to a 7.1 setup with an Onkyo TX-DS787 (already have).
Question 1: Why use the specialised surrounds and not M1's which are less expensive and seem to be rated better for the surround and surround back pair?
Question 2: The Onkyo only support built in amplification for 5 channels. To go 7 I need a 2 channel standalone power amp. Can anyone recommend a low cost clean unit?

Thanks
