Audioblazer, sorry I have been monitoring this thread. I really have little to offer about using the ARTs in a Rive room. I do suspect that they would fight each other, however, given my experience with the Holographs, which I ultimately sold.
Placement of each element is quite critical. I would call SR and ask them. They recommend using Holographs, however.
Ozzy, there price was somewhat of an obstacle. I got them at a "show special" price, but had I not heard the demonstration, I still would not have bought them. Given the price of the little, rival cups, however, they are not outrageously priced. They are far more effective. Yes, they are steel but I know there is careful reheating and tempering that has to be done individually.
I now have a home in New Mexico where I will spend five months of the year. I have a small listening room there and think I must either take my existing set back and forth or buy another.
