After several years of bliss with my old very tweaked out TW40X81, it is time to upgrade. While I have toyed with the idea of going plasma screen, DLP, or even high-end LCD, I keep coming back to CRT as the gold standard display device. And I like the colorimetry of the Toshibas. Since my last purchase, though, I know Toshiba and other manufacturers have experimented with upconversion of 480p signals, resulting in lost resolution and fine detail and increased artifacts. My question, particularly for those who push their equipment (like Michael_TLV, Errol, and Chuck Williams), is: Which of the current Toshiba models do you recommend for good colorimetry, native 480p, and overall tweakability?
