Yesterday I installed a Supra RGB Scart - Scart cable to go between my Sony 725 DVD player and my Loewe Aconda TV. Just to say that there is a visible improvement over my existing £40 job. On a good DVD you can turn the sharpness on the TV right up and all you get is extra detail and not noise. The cable doesn't carry any sound (I haven't proved that yet) and is directional, which isn't something that I have come across before on a scart cable. I also tried out a Supra X-ZAC toslink cable. Results here not so good, I could here a loss of volume and maybe detail compared to my existing coaxial cable. Could be that Sony player or the Yamaha Amp prefer coaxial.
