Neil ,
Best of luck with new toys smile M's own Speakerlink details are up on Duncs site here :

http://www.Meridian-audio.info/show.php?compid=223

and this site has some very easily digestible articles on various types of cable , particularly HDMI , and sell Cat 6 on a roll :

and this site too has good info but won't ship to UK :

I got some good quality Cat 6 in a local computer shop for my own setup and it works like a charm .

Mostly harmless. Comfortably numb.
