Hi, Albert:
It's always good to hear from someone with a fine system that it's possible to assemble a high-resolution system for a reasonable amount by buying on A-gon. Most of my system, including all of my speakers, pre/pro, and power amps, were acquired from sellers on A-gon. The money I saved allowed me to build a much better system than I could otherwise have afforded. I realize that it's hard to avoid personal bias, but I found your comment about the Vandy 3A Sig's gratifying, They can form the foundation of an excellent, reasonably priced audio system. Getting a used pair simply makes the price-performance ratio even better.
Since you have a friend who is a Vandy dealer, you should by all means audition the VCC-5. If you do, please make a follow-up post and tell the rest of us what you think of this center channel speaker.
