Installing a new Home Cinema - any advice on speaker wire.I`m going to need about 60 metres and have been told the GALE XL189 (99p per metre at Richer)would be good - is it worth the extra for the XL250?(1.49). Any others more suitable ??(UP TO £2per metre) Also ,anyone recommend good cables for connecting a pro scan dvd player. I`m told I need 75ohm Component cables - All I can find are ordinary RCA CABLES rated at 50 Ohms. All help gratefully received !!
