Add a good subwoofer for HT if you like your main speakers. The salesman is doing what all salesmen try to do...make you discontent with what you have in hopes that you'll buy the latest "hot" item. It's not like he doesn't profit when you fall for his line and buy his goods...:)
speaker degradation question
I know this isn't a brilliant question, but every salesman I speak to obviously tells me to replace my Linn Helix front channels because they are 8 years old. I burned them in properly and they still perform perfectly. I am told to upgrade because they were not designed for both HT and Stereo. Thoughts and suggestions appreciated, thanks.
