I started with a set JBL's (E-90 mains, EC-35 center, and Infinity Beta-250's for surrounds). Hanging around the Vintage Polk forum has turned me to Polk :D. I now have a set of Monitor 10's for my mains and have added another set of Monitor 10's that I have for my L&R surrounds, with a CS-350 for my center. I still kept my JBL E-50's for my rear surrounds as they are mounted up on the rear wall and do blend with everything else. The mains and center are a excellent match. I went through several movies tonite as well as some CD's and I'm in audio heaven! Thanx guys for the tech help.
