Are HDTV component cables realy necessary for my new HDTV set, a Panasonic CT-36HX41, or will standard component cables suffice, like the ones I had used for the Colorstream inputs on my Tosh set? I will have the Tosh SD4700 progressive scan DVD player hooked up to my new tv, once it ships, but am wondering if I really need to upgrade cables or not. A friend of mine mentioned the HDTV component cables from Monster do not drop below 75 ohm, or something like this. He was talking over my head, but it is now making me wonder if I do need them? At $89.99 a pair, and needing two sets, one from the DVD player, and then one set from my Denon 3300 to the Panasonic tv, this could get expensive quick. Any advice appreciated. Thanks.
