My very 1st post on the Klipsch site but a long time Klipsch owner so if I post incorrectly a helpful suggestion would be appreciated. I now have a Denon 2700 5.1 AVR and upgrading to a 3310ci which delivers 120 watts per channel. I have KLF 30's for the front,KLF C7 for the center and KSP S6's for the rear and a KSW-200 for sub. My amp now has 85 watts per channel and the new one is rated at 120 per channel which brings me to my question, buy a pair of used S6's rated at150 watts or buy the new S2's which are rated at 100 continuous power. Any comments? Also does anyone know where I can purchase a pair of S6's white or black (preferred) but either will work. Emails would be great and a response to the post so I know if I'm posting correctly. Home email is kee68@stans.net. Thanks in advance. Bob
