It is a given that both sets display superb pictures, according to professional reviewers from S&V, Perfect Vision,Home Theater, and E-Gear. I compared the Toshiba at ABT and it was difinitely better than every RPTV in the room except for the Mitsu 65711 Diamond where it was a toss up. I have not seen the rca 65inch scenium on display anywhere, only the 61inch. The toshiba and rca are about the same price. Toshiba: excellent crt with 6 element lens, dvi inputs, slick upconversion circuitry IDSC pro, cable clear dnr, 720p input, fine pitch screen 52mm, 1200 lines resolution, excellent stretch modes, rich looking cabinetry. Rca: dvi input, Firewire input, built in web browser, built in terrestial hd receiver, 720p input, fine pitch screen 52mm, 1400 lines resolution, 30 watt sub, 7band equalizer, motion adaptive upconverter, and the best looking cabinet around. The toshiba seems to have the edge in refining analog signals and in stretching modes. The rca has a big edge in future proof with both dvi and firewire and throws in a terrestrial hd receiver (a $300 value). Toshiba has been pretty reliable. Rca has fixed earlier problems with lockups. I am having a difficult time deciding which set to purchase. Will appreciate any input or opinions.
