Thanks in advance for taking the time to skim my situation. I'll try and keep it concise. Eager to dive through the forums and absorb all that your big brains (& ears) have to offer. Apologies in advance for my newness and lack of proper lingo. :)\n\nHere's the equipment I'm currently working with that I've had laying around for more then few years. I'm immediately looking to upgrade the aged AVR, but shortly thereafter looking to address obvious (not to me) weaknesses in the system & expand it to a 5.2.4 setup. \n\n- Receiver Yamaha - HTR-6295 (she old)\n- Fr L & R : Energy RC-70 towers x 2\n- Center : Klipsch C-20\n- Surrounds: Energy Veritas V-S x 2\n- Sub: Klipsch: SW 112\n\n1st: AVR upgrade thoughts:\nCurrently trying to decide between the Denon X4500H, Denon X3600H, or the Yamaha RX-A2080. The Yamaha appears to have the most power, but the least powerful X3600 has the greatest channel options down the road with added amplification. I know I've read that power differences this small aren't significant, but then I read reviews that seem to focus on the punch or power of one receiver versus the other with similar spec differences. \n\nMy current AVR has 20 Hz to 20 kHz, 0.08% THD, 8 Ω . 130 W. Am I stepping down in power with the X3600 to 105 W just to get all the updated feature goodness?\n\n2nd: My towers specs show – Recommended Amplifier Power: up to 250 Watts. Does that mean per speaker? Or total amp power?\n\n3rd: Just looking for an overall assessment of my kit & if there's specific components in it that you'd recommend upgrading (other then the AVR).
