I thoughit was too good to be true. Yup, it was. The thing almost blew the speakers out of their cabinets when I switched the standby off. My (or formerly my) tech did not charge me this time. But you get what you pay for.....NOTHING! It is going to Boston tomorrow. It will take me two trips 2hrs each way. But Gibsongeek steered me to HIS tech there. He WILL make this thing right. I don't even care how much anymore. This will not defeat me. It should have tipped me off when I was told--"these are fragile, don't run it on top of the cab" FOOEY!!~!
