I sold Robert my SinglePower Extreme. He was very pleasant to work with. I must say I feel bad though, as due to a mix up, I made him drive an extra hour out to my house to pick up the amplifier.(I thought he was at The Colusa Casino, he was at Cache Creek, that's what I get for trying to look on google maps while half asleep) Sorry Robert!
Hopefully the amp will treat you great and you will have more time to spend with it than I did.
