I am planning on installing a Home theater sytem in steps and have pretty much decided on Klipsch Referance IV RF-62's with a RSW 10d sub. Anyone have these?? Any opinions on them?? Out of the HK-347, Yamaha RX-V861, or Onkyo TX-SR 705, which would be the better rec to push these?? Would an amp be needed?? I don't listen quietly but I wouldn't say I play'em loud either. My listening habits could be summed as : High mid-range volume mainly from Blu-ray, dvd movies, games( PS2 & 3, Xbox, Wii), music and minimal tv.
