We get together once in a while as a group. I've met a couple folks that I now get together more frequently with, including Scott(Soliver), who sort of keeps the big group organized. He has a list of all the people who have contacted him over the past couple of years. If you want to host something, then he's probably the one to contact first and I'm sure will help to get the ball rolling. It's probably time to have another big get-together so that folks can meet each other. The big meetings tend to be more social, which is good imo, because hopefully, you'll meet some folks you like and then can pursue smaller get-togethers where more serious listening is likely.
Anyways, glad to see more Austinites interested in Audio!
