I am looking to purchase some new flat cable. It has to be flat so I can run it up walls & colur code it to keep the Mrs happy. I need to do some longish runs i.e. 10 metres After some research I have found two types at similar prices for 100m reels (£60ish) A couple of questions if anyone can help One type of cable is 152 strand & the other is 79 strand OFC. What difference does OFC make i.e. is it better to have more strands or OFC with less strands. I have 3 main(front) speakers at different distances from the amp, is it best to use identical lengths or does this not make any difference. My amp is Marantz 5400 ose & my speakers are Bose Accoustimass(yes I fell for the hype & trade in deal but have to live with them now...they do look good!) All help suggestions appreciated!
