From an audiogeek friend-- over 3 years ago-- and my audio life hasn't been the same since. Audiogon has cost me a lot of money and saved me even more-- this is "audiogeek logic".
My audio knowledge has increased exponentially, and my stereo system is now truly high performance, but I think most of all, I've enjoyed the interchange of information and ideas (even the weird ones) on the site and meeting fellow audiogeeks. Cheers. Craig
