Come on guys, cut him a break. That was his impression, and heck, he might have been using an HD70 and then an RS1. The proof is in the eye of the beholder.
As i stated in another thread, when I went from 480P to 720P unit I was not in the least blown away. In fact I was going to sell the 720P unit, but then with properly setting the unit up (Calibrating it) and buying/adding the same cable structure (DVI/M1 & Hdmi) and doing a side by side comparision, I then saw the incredible depth or 3d effect (Ansi CR and colors) and kept the unit (Although not earth shattering, but have come to love the adjustable Iris and way extra lumen output). Although at 17' seating distance from a 110 inch screen I doubt that a 1080p PJ would be much better than my 1200 dollar marantz vp4001 unit. (DLP, 500:1 ansi, 6500:1 CR, 1179 full Lumens)
