Welcome to AC and the North Texas circle, Scott!
I'm not currently aware of anyone living in Abilene or straight West of the Metroplex. We have a few guys split (mostly) between the North and South sides of Fort Worth, and Danny Richie of GR Research is located out in Iowa Park, TX, along with a few others. There may be other audiophiles closer to you, but I don't recall seeing any others on Audiocircle just yet.
Is there any chance you visit the Metroplex on occasion? We haven't had a big jam in a few months now, although there have been several "micro" jams that have popped up as people get a new piece of gear in that others may want to hear. Art and Oscar have talked about hosting a larger jam in the not too distant future, although most of the guys are generally willing to host individuals on an impromptu basis if a visitor is interested in something in particular.
Hopefully you'll be able to join us as opportunity allows!
