Upgrading from the JVC RS2 to the RS40...worth it?

post #1 of 14
Thread Starter 
Hey guys,

I have an RS2 which i love using it on a Carada Brilliant White 120" 2.35:1 screen with a Prismasonic 1500 anamorphic lens. After about 1,000 hours it gets pretty dim.

The RS40 is a hell of a lot brighter at 1300 lumens and also it's 50,000:1 compared to 30,000:1 for the RS2, but will the image quality (colors, film-like appearance) be as good as the RS2?

Also, not that concerned with the 3D side, I'm more doing this for the lumen levels and better contrast.

Cheers.

I am not going to talk you out of it, but let me give you a bit of some facts that you have to be careful with.

1. The RS40 is rated at 1300. However, that is absolute best case...shortest throw, high lamp, brand new lamp, iris fully open, and still there is some variation.
2. The RS2 was rated at 700, same setup. Now while it is a large number difference, the RS2 lamp dims generally slower over time, and, what would appear to be a nearly 2x increase, to the human eye will not appear as such. Yes, the RS40 is brighter. But I wanted to make sure you understand the reality of the difference.
3. The contrast on the RS40 is 50000:1, vs. 30000:1 for the RS2. Again, depends on setup. The RS40 only does potentially 50000:1 at the EXACT OPPOSITE settings as above. You won't get 1300 and 50000:1. Moreover, here is how contrast works. It is white level over black level. Say the measured white level of the RS2 and RS40 was the same, say 100 for a random number. To go from 30000:1 to 50000:1 would change the black level from .0033 to .0002. Your eye will never see that in reality, especially when actually watching a movie since it cannot possibly change that fast with the content.

Again, I am not trying to talking you out of it. But, really the differences in the 2 should be looked at in other ways as well. The RS40 has a fairly accurate color setting unlike the RS2. It is 3D (take it or leave it), the panels are generally better and have better uniformity, no bright corner potential. The lens is a bit better made, including the shift and such.

So you really have to look at it from a whole, because if you merely are looking for light output and contrast, you may not be as happy as you hope, if you are thinking about the numbers as most do.

My 2 cents.

I would go for RS45.

Thanks Jason, all good points. From what you're saying it's a pretty minor upgrade.

I was hoping the 1300 lumens I the RS40 compared to the 600 of the RS2 would be a bigger difference.

Why does the lamp in the 40 age faster can I ask?

Gradius I'm looking at the RS40 as there are some good deals going on them.

In general my outlook has been to wait for 3D to mature and also hopefully start to see projectors with LED lamps or a similar tech that will last 10-20,000 hours. I'm wondering when this will be and in an affordable $4-7k range.

I went from the RS2 clone (FPJ1) to the RS45 which is just about the same as the RS40. Black levels are about the same. My RS2 clone had no bright corners, my RS45 has slight bright corners but unless it's a full black screen I rarely notice it and I am fairly picky. I use the RS45 with the iris clamped all the way down on normal lamp (RS2 was on normal lamp) and the RS45 is noticeably brighter. My RS45 also has a sharper image (you don't need a test pattern to notice the difference) and personally I like the CFI quite a bit. Even without CFI motion is still better. Personally I am very glad that I upgraded and while the 3D image has issues I'm still enjoying occasional 3D even with the flaws. Most others who come over don't see the flaws which I find entertaining.

Again it is a difference, just in a persons head more than in the real world...just making sure you are careful on expectations.

The lamp is run harder on the RS40. Not just the JVC, it depends on the unit. Business projectors do the same to get higher light at first, as do some 3 chippers. Not uncommon out there...

The story ends with me taking the plunge. Anyone wanna buy a much loved RS2 with a new lamp in the box? biggrin.gif

PM me if you do.

You will love the sharpness of the RS40 or RS45 (whichever one you picked up).

An RS2 is what, 5 year old technology? I don't think anyone ever recovers much cost in a 4-5 year old PJ sale. Even a JVC. Most guys ask way too much for them, so they sit. Wanna buy an RS1?biggrin.gif

Your probably asking too much money for it. just kidding, but I know what you mean. I still have an old Marantz VP-12S4 sitting around.

talk about depreciation, I don't know if overclocker is still on AVS but I see that he is selling his stacked G90 crts on videogon for what must be a HUGE loss financially eek.gif

He has decided to stand pat for now.

I don't remember how much he paid or if he ever said, but he has had them for awhile.

Thanks again. FYI depending on certain factors (condition, lamp life, etc...) I would say an RS2 is worth ballpark $900-1000. Of course some may get more, but not likely.
