I've recently purchased a 210E and a Yamaha E800 processor, which sit about 3 metres apart in my living room. Being a bit of a skin-flint, I bulked at the cost of of 3metres of optical or coax for the digital audio signal, and decided to try out a cheap phono wire (not 75ohm) that cost £3.99 from maplins. I wasn't entirely suprised to discover that it seems to work perfectly, as being digital, I would expect any signal flaws to be obvious - silence, noise, clicks etc, but it's perfect. In a similar vein, the thin .75metre s-video cable that came with my computer's video card provides an excellent picture when connecting my tv and dvd (I don't have RGB or component inputs) and I can't see how picture quality could be improved with different cables. Even maplins cheapest I also purchased a 1.2metre 75ohm video phono cable for £2.99 which I use to connect the digital out of my cd player to the Yamaha, and again it sounds perfect. (How can digital cables sound different anyway?). An even cheaper phono would probably suffice just as well, as I am lead to believe the 75ohm rating doesn't come into play until the cable length is much longer and it begins to act as a transmission line. So, am I insane to think fancy cables (esp digital ones) are a waste of money?
