I am new to home theater. I have just purchased a set of used Quintet III and a 10in klipsch sub. I am using a 4yr old Panasonic a/v receiver that delivers 50w/c. I would like to move up to a str-da5200es rated at 125w/c. Is this to much power for the speakers? If so what a/v receiver would be a good match for the speakers. I am going to purchase a lcd/plasma tv in the near future. Thanks for all your help and advice. Gregory

I am just starting to set up my new house with high end sound equipment. And am in need of some advice. I am 53 and would like to buy equipment that might last a life time. 1. Is there a difference between home theater and surround sound? And what is the difference if any? 2. I will have no cable or satellite tv. So I would like to match my reviever to the speaker any ideas? thanks abunch
