Thanks. I had a chance to check out the 630 over the weekend. I can't really comment on overall picture quality, as the demo set was completely tweaked out--max contrast, brightness, color, you know how they do it.
I did demo the amp feature (via the split screen demo). If you are watching casually, and if there is little movement on-screen, it's hard to tell if it's on or off.
However, with (very) fast moving images, such as with sports, the difference in clarity is noticeable and appreciable. The same holds true with scrolling text.
I did not notice any strange artifacts with amp turned on. However, I was unable to verify the exact setting--aside from the fact that it was on "demo mode," whatever that may mean as far as specific amp settings are concerned.
Overall, I'd say it's a useful feature for sports, and more or less unobtrusive or just plain unnecessary with other sources.
The source material in no way resembled shoddy video material (i.e., the so-called soap opera effect) with amp on. Film still looked like film.
From my brief demo, it appears as if amp works pretty darn well--meaning it works when it's supposed to, and doesn't change image quality noticeably otherwise.
I must say I am still quite happy with my 60 hz tv, but this is a feature I'd be happy to shop for in the future.
