Thanks to Audiogon and friends

Please be easy as I'm a nubile/novice/non-audiophile. Having said, I thought that I was the cat's meow. Friends and associates agreed. Now, please don't laugh. I have a HT/Surround system from a "high profile" manufacturer(it starts with B) that I, uneducated, thought was ideal. I was using the system for both HT and stereo audio. I thought it was great until I visited an old friend that had Rega gear. Suffice to say, he and Audiogon have awakened me. My surround system is great for "club sound" when I have a gathering, but is inferior when it comes to true music. I am begining to build a system with a small budget(I've started with a Cambridge Integrated). Needless to say, even wth a low budget amp, the difference is astonishing. Audiogon has been a great resource. Any further insight would be helpful. Please bare in mind that I have a limited budget. Thanks, audiogon members.
