Give em a little time, I got M60 front VP150 center 3 QS8 surrounds Klipsch 10" sub. I definetely heard a difference after about 100 hours of play. I even left music on while away. I didn't hear much difference when moving them around but after breakin I definately heard a difference and I have an inexpensive receiver, a Dennon AVR 883 80X6 Watt at 8 ohm. I must say that I had 1970's equipment Technics SA-5460 65X2 and Pioneer HPM 100 speakers that didn't need a subwoofer. I would have to call the 2 systems close to equal for music. What is amazing is that I tried the Pioneer speakers with 5 different 2 channel and surrround receivers ranging from 75 - 110 Watts per channel and none of them could poduce the bass from those Pioneers like that old Technics receiver.
