Update number 1....EV tech service = Grade A..called up the 1-800 number and spoke with a service rep in about 3 minutes (descent music on the tape too) Told him about the buzz in one speaker, he said to bring it and the receipt to my local Ev service contractor (I have one 20 minutes from my home...lucky me)and he'll test it and get it running right. if there is a problem and they can't fix it...they'll call Sam Ash and i can just run down to new haven and pick one up. Badda Bing....I'll let you know what they find by the weekend...Thanks everyone..Brian
