hi all, I just got a 750 from ebay. unfortunately the great UPS (see other thread) dropped the box and the 1st channel's positive speaker post is broken off. Would it be worth my while to fix this myself- I can solder etc. or is this just too much hassle? It sounds great otherwise- but I have an agreement with the seller to return if I want to. I'm leaning on returning, but just wanted some expert advice. Thanks in advance.
