thanks for the scoop on the han-01 bill. i hope my next ir543 works better. i had never heard that magnetic interference was an issue with the ir543. so that means that i wont put my new one on top of my powered sub like my first one. you're right about the ebay deal. i didn't think about the shipping until afterwards. the good thing about our sponsers is that they respond and help the rest of us. my apologies to the sponsers.
