Its a onkyo tx-8050 2 channel..and ofcourse i dont think that mark thats why im asking for opinions..i got the rf 7 iis bc they are a significant upgrade from my rf82s and i got a insane deal on them.they sound absolutely amazing i was just curious how "much" im missin out on,on there full potential with the reciever im using..i really like onkyo from my experience with it on my 82s..i really dont have a price range.i suppose id spend anywhere up to a grand if the difference would be justifiable for the price diff..i dont care about bass..there not in a huge room and they sound plenty bass heavy now and rock and softer acoustic stuff is what i listen to mostly.thanks
