Small Amplifier

KingMeander

Hey, I have bought an inexpensive multi-room speaker set up (For upto 6 rooms) and have the Onkyo 705. I only plan on putting speakers in 4 rooms at the moment (as that's nearly all the rooms in our house) and wanted to find out if I should buy an amplifier to go between the reciever and multi-room selector. If so, any suggestions would be good, and I am on a small budget (so no $400 or more amplifiers).
