I somehow misplaced the 'audio input cable' and I'm in absolute misery at the moment as I'm not being able to play my system. No luck with eBay as I've checked multiple times and have found none available for purchase. Where do I find an audio input cable new or even used but in proper working order? Are there other Bose system's with audio input cables compatible with my system? Help desperately needed, I'll be really grateful if anyone can help me regarding this matter. Thanks in advance.
