the a/v receiver part of this system is broke and out of warranty. i wanted to buy a new receiver and just use the speakers and self powered sub-woofer, until i looked at the connections on the back of the sub-woofer. it uses what samsung calls a 13 pin din cable to connect it to the a/v receiver. this is some kind of proprietary or at least rare cable. so does any one know of a 13 pin to rca or any kind of converter cable so i can use it with a regular hook-up to an a/v receiver. if not i am stuck with a receiver that does not work very well and a sub-woofer that will not work with any other receiver. the only thing i can salvage then are 4 tall speakers and one center channel speaker. needless to say i will never buy any system with proprietary cables again. to bad i did not know this before i bought it. thanks in advance for any help.
