The audio side of my home theater consists of the following: A/V Receiver: Harman Kardon AVR 8500 (named AVR 8000 in the US) Center: Klipsch RC-7 (98 dB sensitivity) Mains: Klipsch RF-7 (102 dB sensitivity) Surrounds: Klipsch RS-7 (98 dB sensitivity) Subwoofer: None (but working on it) My Harman Kardon AVR 8500 (or AVR 8000 for the US) outputs 110 watts into 5 channels while operating at full power. In stereo or 2-channel mode, it outputs 125 watts to both channels. I've heard that Harman Kardon is quite conservative with its watts rating and Harman Kardons usually output more than their advertised specs. This was the last true high-end Harman Kardon A/V receiver and it sounds great. I heard that the replacement high-end Harman Kardon is coming soon and is named AVR 7550HD and outputs 110 watts into 7 channels. I have never had any problems regarding power and no matter how loud I play it (even with the mains running as Large due to no subwoofer), the A/V receiver never shows any signs of stress. I might be upgrading my amplification side of my home theater soon to incorporate the new Blu-ray audio formats. I can get either the new upcoming Harman Kardon AVR 7550HD (which is said to retail for about $2,799) or a Rotel or Parasound 250 watt amplifier + processor combo for about $6,000 (I can probably get a little discount from $6,000 as this is the maximum sales retail price). My question is, will my speakers benefit from 250 watts per channel separate amplifiers or will I not notice the difference between them and the upcoming Harman Kardon AVR 7550HD with 110 watts into 7 channels (or even my current A/V receiver with 110 watts into 5 channels)?
