Hi - I'd like to set up a descent system in my 1200 sq ft art studio. This will be used as audio only. I inherited the following speakers: 2 x Polk RT12 (mains) 2 x Polk M3ii 1 x Klipsch KSW10 Sub What Receiver or Amp can I get to power these speakers? My goal is to not get something that will be overkill since I will only be using this system to play tunes from my Macbook Pro via optical cable. I also have an old Denon 3300 that needs about $250 in repairs. Is it worth repairing to power this system or can I get something better/newer for not much more? Thanks for the help!
