Got a Cobalt for my birthday (thanks, bro!). Easy to install (thankfully, Oppo provides an HDMI cable, so I had an extra. Too bad Darbee doesn't, especially with the apparent importance of the length), and so far it's working flawlessly. No handshake issues or dropouts, despite switching frequently among Blu-ray, CATV, and AppleTV. It just comes on when it's supposed to and works. The menus are easy to navigate, including turning down the LEDs, removing the persistent logo, etc. The remote works well, and I actually think it's kinda cute.
How's it look? Hmm, too soon to tell. I've always been partial to high-contrast images (less important now with HD), and that seems its major effect. There might be a slight color-shift (towards brighter, or even bluer), but I'm not sure.
I might make a comment similar to the guy's wife upthread: can't you just use some of the settings on your fancy, expensive HDTV to provide similar effects? You'd think, but we're told by the experts, "no," because it introduces too much artificiality, from "ringing" to you name it. Likewise, "soap opera effect." I've become pretty much inured to that by virtue of leaving my Samsung's Motion Plus on all the time. I don't even notice it anymore.
Not with the Darbee. My SOE is way more apparent now. Is there any chance it's doing some kind of frame interpolation? I don't see how, but thought I'd ask anyway. My suspicion is that it's a depth-of-field issue. That's really the problem with SOE--live and video-based sources always have so much more in focus than does film, and it bothers people. With the Darbee, there's a lot more detail, especially in the background, which mimics this.
So, is it really better? It does look sharper--turning it off seems to shift the picture slightly out of focus, and that's annoying. (Maybe that's what the Darbee really does: degrades your picture while making the processed image look normal. Clever!) And, it is absolutely true that the best results come from the best sources: Blu-ray definitely shows the greatest improvement with the least amount of adverse effects. Streaming and cable HD sources fair worse, with macro-blocking and compression artifacts being even more noticeable with the Darbee. I don't see how it could improve SD or YouTube videos, even though that's supposedly what the Pop setting is for.
Oh, and I should point out that my now-five-year-old Samsung 52-inch LCD is really the perfect platform for this. I've had a recent boost in picture quality thanks to the VP chips in my new Onkyo AVR. I was hoping this would really put me over the top.
I'll keep watching and let you know.
