I don't know how many of you attempt tweaks to try and improve your A/V systems. I have tried several, such as expensive wires, isolaters, etc. Usually I end up trying to convince myself that it really did make a difference and it really was worth the extra cost. Then after I convince myself, I try to convince my wife and friends. They are usually brutally honest and vary rarely admit to being able to detect ANY difference. I recently installed a backlight behind my Toshiba after reading about it here and Lo and Behold, they finally saw a difference. I got a universal thumbs up from them all. For some reason, not totally understood by me, this really makes watching DVD's more enjoyable. Eye strain is gone, colors seem more intense. One of the best things about it, to me, is it was not expensive. Nine dollars for a 24" single tube fixture and $4.00 for a Phillips Daylight bulb. If you like subtle changes and have not tried this yet, give it a shot, you will like it.
