Hello, welcome!
I'm NE of you, just east of Parker.
RMAF won't return from what Marjorie (the organizer) said. The T.H.E folks said they were going to have one here last year, but that didn't happen and I'm not holding my breath.
As for dealers, the folks at Soundings in Centennial are nice and carry stuff from affordable to ludicrous.
There is also aural hifi on south Broadway. They specialize in vintage/mid century audio, but the do have some newer stuff and some of it is very nice. They have a great service department. Very nice folks.
There is also a local audio society/club, ColoradoAudio.com, the site lists upcoming events if you want to attend, always good to have new folks.
