Audio Concepts, a really great local dealer, carries Quadraspire, Salamander, and HRS.
One of our members is a dealer that owns "The Audioguy" in Lewisville that I believe carries Mapleshade racks. You can certainly call him and see if he is going to be opening back up next week.
I'm sure other members will chime in with recommendations as well.
As far as the audio club itself, we have what I would consider a very active club(pre-COVID). Joey does a tremendous job organizing the group activities. The meetings I've attended have allowed me to hear some amazing systems, but more importantly the guys in the group are all outstanding individuals and are extremely helpful for us with more modest systems looking for advice.
I hope we get a chance to meet soon.
