I understand that. It's not an option for me anyways, for the other reasons stated.
But to address the audio issues there seems to be some people who have done some research. From what I read the amp certainly will work on a 15 amp circuit, because it has a built in limiter on it that will prevent it from drawing to many amps, which will in turn lower power output.
There were tests performed and I can't remember if they were tests of the actual Triax or the amp the Triax uses. In any event the tests were performed on a 50 amp circuit, 120 volts. As was said in the Audioholics post, which you've probably read, not many people have 50 amp circuits in their home. It was thought by the posters that a lot of people will get much less power because of the limiter and the use of a 15 amp circuit.
Honestly, I read the thread and that's about it. At no point would I consider a Triax, because I've read too much about the benefits of having 2 subs in different locations, and two Triax boxes would be much much more than I would want.
The fact that Tom V. is from SVS, while that's great, doesn't mean the Triax will not go through it's revisions over the years. Maybe it won't, but it's likely it will.
When I was younger and had more money to throw around on material items I could have cared less about a product being first release. The older I get the more my priorities change. I find myself looking at things I never used to like warranty, return policy, history of an expensive item etc.
The Triax looks like a bad ass sub setup, and I'm sure it will be.
