Much improvement upgrading leads ? I have some over priced monster cable for all my speakers however I havent purchased any uprate leads except for a profigold DVI lead for my HCPC to TV. I have 2 cheap optical leads which are used 1 for my HCPC and 2 for my freeview, both are quite thin. I have a RGB > SVIDEO lead which again is the usual cheap spec black free with system. Cheap black free scart with freeview. Would I notice an improvemnt if I was to get a better quality cable for the video and the digital sound ? If so what cable would you recomend ? Place to buy online ? Brands that are good etc. I know currys stock JVD cables are they very good or overpriced ? Thor cables ? And retailers comets currys etc that stock them. Thanks in advance. Evo.
