I have just had a dem for a 406. I have to say i was a little dissapointed as other than a little less noise i could see little difference in the image. Having never seen a scaler work before maybe i was expecting too much, my dillema is that the engineer who set the 406 up had little time to set the 406 up correctly and was using s video on a 720p output. If set up correctly does anyone have an opinion on whether i would get a reasonable image improvemant ? My eqipment is as follows; sony D50HTM CRT Projector 64 hz with built in line doubler, sony es9000 dvd player [region 2 discs only ] 1.8 Meter perf screen.p.s. sony uses 7 Inch tubes 3 meters from screen. Many thanks to those that reply .
