Me. Not only that, I also built the only remote control A/B projector comparator switching machine I am aware of. It's rickety, but fully functional, and makes for an easy and quick A/B switch from my normal viewing chair via remote control. [As far as I know, not even professional reviewers have such a device and instead rely on either visual memory, which is notoriously fleeting when evaluating subtle differences and not "photographic" at all, or at best use manually placed light blocks alternatively between the two DUTs (devices under test) while standing right next to the projectors as oppossed to their normal viewing positions. By modifying an old out of service CD player I no longer needed, mounted vertically, I was able to use its remote's eject button as my A vs B comparison button:
[please excuse the shaky handheld cell phone video; I was pearched on a ladder holding the CD payer remote in one hand and the phone in the other. Only one projector was left on for this demonstration video, as you can see, but obviosly both are turned on when actually under test.]
Well that's the good news, now for the bad news. Although I was indeed able to see some differences, it was impossible for me to tell for sure what differences were due to the actual projectors vs. the nearly 1000 hrs of extra run time I had on the 1 year older 3000 vs the brand new 4000.
Bulbs dim with age, without a doubt
, and I would assume may have slight color shifts as well.
Although the 4000 seemed
to have the edge in absolute black level (darker), it was subtle and only evident on test patterns, not actual TV shows or movies, including space movies like Star Wars where one sees spaceships against a black star field background. Then again the 3000 has two sets of component video in vs. the 4000's singular one.
Overall I'd say the difference in IQ is subtle. Ignoring the fact that the newer 4000 will have much better resale value a year or two from know, and pretending this is going to be the last projector ever bought (LOL!) I'd say the difference is worth 2 o'3 hundred dollars, 4 to 6 hundred if you are picky, and not worth it for $700 or more difference, but that's me, your mileage may vary, and then again the bulb age difference makes my evaluation questionable. Good luck.
