Thanks for info Peter. Perhaps I may have jumped the gun, shortly after running the amp one of the channels has a problem. I thought one of my drivers may have blown but it turns out it was one of the amps channels. I moved it to a previously unused channel and everything sounds much better. I waited a week for it, I hope I won't be with out the amp for weeks. Maybe they could send a replacement modual for the bad channel and avoid all the shipping hassels. I had to do this for my ATI 6012. I will contact them tomorrow.
