Anthem ARC is very good.
I use their preamp only and run multiple amplifiers to the speakers.
My listening room has a wall of glass on one side and it is still able to get an almost flat curve.
Works for two channel and home theater.
'Anthem Room Software
I want to use/purchase anthem room correction software, but am unsure how to implement. I have a stereo amp and preamp, both tubed. Anthem sells the gear to test the room and generate a room correction file. But what about hardware that will interface with my amp and preamp???
