After having said that I was using cheap scarts on my new TH37PE50 (cost £4.99 each four years ago gold plated the packaging said, but I would think gold effect) I was advised to buy top grade scart leads by a number of forum members. I remarked that the picture via Sky with the cheapo leads was stunning and I doubted that I could improve the PQ beyond what I had already. Anyway to cut a long story short I contacted my Panasonic dealer who advised me to pop into the store and to bring along one of my scarts for a comparison test. The results shocked the dealer. He first connected my scart and played a DVD which he said would sort out the men from the boys PQ wise. As I suspected the result was very good indeed even with my cheap lead. The dealer then repeated the exercise with an IXOS mid-range lead costing about £35, result both the dealer and I could not tell any difference. Astonished by this the dealer then tried a top of the range IXOS costing £55 each and a Monster cable of similar price. By now we had been joined by two other sales assistants and two customers. We ended up on our hands and knees looking for any differences e.g. solarisation or lack of detail five people could not detect any difference. The dealer then placed a second panel at the side of the first one and connected one using the top of the range scart and the other using my cheap one then played identical DVDs. Again none of us could detect any difference, although one salesman thought that the reds on my cheap lead showed slight bleed although if you have to get on your hands an knees to see it then it hardly matters. The dealer admitted he was truly amazed by the results and told me to hold on to my cash and stay with my cheap leads. Now although these results are not scientific, certainly in my case spending lots of cash on top grade leads would be a waste of money. On a slightly different tack the dealer was also running the PV500 and the PE50 side by side using the Panasonic Hi Def demo obviously the PE50 was receiving the feed via its analogue component connectors. The results are truly amazing the PE50 produces results equal to the PV500, or if not equal then certainly both I and a number of other people in the store at the time could not detect any difference. Thats not to say there is no difference as obviously there must be, Im simply saying that viewing both these TVs from close up to a distance of ten to twelve feet away I could not tell any difference truly. Im sure others will disagree with my experience regarding the above. However, all I am doing is reporting the results I have found using cheap scart leads.
