I'm aware of the never ending discussion on interconnects and speaker
cables, but I just want some advice on what to actually buy. Nominal
impedance of speakers is 6 ohms. Room is quite large and so
amp/speaker distance will be 4-5 meters. Speakers are bi-wired.

I just need an idea of cross-sectional area and where I can get some
suitable cable. I'm not convinced by the talk of OFC and so on.
Multistranded copper of sufficient thickness is fine by me.
Suggestions please ?

Just get a decent thick cable, 2.5mm mains or bigger - or preferably
flex - will do.

You are right, there is much rubbish spoken and snake oil out there,
but given that you have a fairly long run then thicker cable is best
so that it doesn't become significant in the damping factor of the
speaker/amp interface. (Mail me off-net if you want that explained.)


Thanks, I know about damping factor and the need to keep cable resistance
well below actual speaker impedance across the audio range. I did some rough
calcs and came up with a figure of 3-4 sq mm and was curious about what the
experts here suggested.
