Honestly, I've never heard of them. I personally started with a high-end residential integrator, and we saw plenty of 42" to 60" displays, with 50" being the main size that were being installed at $10,000 or so a pop back in the very beginning. For me it was the beginning as well. A couple years later I moved to a Washington DC local chain called Myer-Emco which was pretty much all about high-end. It was fun with them for a couple of years as well. Pretty early in my career so I was job hopping to get significant pay increases. Throughout all of it I started as an AV programmer and engineer with basically ZERO background in AV at all. So, unlike many engineers that come in from installations, I came in from programming (accounting actually!) in a weird career twist early in life.
20 years later, Myer-Emco and that first company I started with are out of business. I've worked for several commercial integrators who have also gone belly up.
Strangely enough... within a few years of me leaving them. Not saying that me working for them causes them to go under, but I'm not saying my leaving doesn't. (ha!)
My love is projectors, but I try to stay on top of the video game at least. Way to many opinions on what makes up 'good' audio, so I just stick my head down and avoid most of those conversations. Give me a nice big sealed subwoofer with lots of power and some tower speakers and I'm generally very happy.
Rockin' my 85" Samsung LCD now in the family room with a 161" JVC front projector in the basement. Size matters!!!
