I think I may have narrowed my search for speakers down. I am putting together a speaker system that will go with the Onkyo TX-SR601. I am not a true audiophile and have trouble understanding why certain speaker manufacturers sound better with certain receiver manufacturerd. I have been told that the Polks would go better with this receiver than say the Infinity speakers. I have also heard the energy speakers and they sound good, but I am uncertain as to how they will sound with the Onkyo. Specifically I am looking at the following: Front: Polk RTi 28 or RTi4 vs. Energy Take 2.2 Center: Polk CSi30 vs Energy Take 1.2 Sub: Polk PSW303 vs Energy S8.2 Rear: In-ceiling (yet to be determined but probably Polk or Niles) Any insight would be greatly appreciated.
