I'm looking to hook my Sky box up to my home cinema by coaxial. Unfortunately, I've only got 2 optical inputs on the receiver, which are both in use. I'm not after amazing sound quality, after it, it'll be for watching normal day to day TV programs. I also don't want to spend £20 on a cable that won't sound significantly better than a cheap phono cable. I currently have my Apple TV plugged in via component, and I'm using cheap Red/White phono cables, and everything is great. I didn't notice any reduction in video quality when going from HDMI to my cheap component way. I don't own any spare phono cables, and all my cables that are in use are tied up/hidden away. So before I buy one, is there any reason this would be a bad idea? I've never dealt with coaxial digital audio before. http://www.maplin.co.uk/phono-plug-to-plug-lead-1019?ordercode=L01BA Is what I'd likely buy.
