Interconnects Advice: NAD M25/M15 and PS3

[D-C]

Hi all,

I'm in the process of buying a NAD M25/M15 HT setup.

Any advice on interconnects between the amps?
Budget of up to and around £200(ish)

Also I play my Films from my PS3(new version with full HD sound) I understand the M15 can't fully utilise this. Is the best way of linking to the M15 via optical? And if so, anyone able to give advice on a good cable?

Also thinking about changing speakers but I'll make another post for that..

Thanks all!
