I did, That may sound a bit silly, but I still had to be convinced, which is what part of my demo/testing was all about. I know enough now to know that I an sticking with Matrix. We have found a great combination with the new amp I'm getting and the RXjnr. The amp produces amazing amounts of power, up to 4000 watts per side into 4 ohms. all the amps whether driving sub, bass, mid or top are great. Everything that was heard at the demos was driven by Switchmode amps.
