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 ?

Go to B&Q and buy some of their loudspeaker cable. The copper is nice and
thick, with lots of strands, and easily good enough for 4-5 metres.
