It should help, but I'm not sure. I know you get the full 1920x1080p with the a-lens but the eshift has more pixels.

The main reason I would consider the X75 is the new bulb and power supply. Seems the bulbs are maintaining brightness quite well and are rated for 4000 hours on low lamp mode, 3000 in high, also have much better warranty. If the warranty has increased, bulb blow-outs must have been reduced as well.


I know that most of these claims are probably as bloated as ever, but I bet they do last allot longer than the previous gen. People seemed to be less than impressed with bulb issues on the X30/X70/X90 line-up.

I would try it and see. You can always get rid of a good lens, better to keep it and see then sell if you find it unnecessary.

ok thanks so the x75 good unit is the x55 a good unit


I was offered an X55 as a replacement for my dead HD-950, and after serious consideration I decided to pay the difference and get the X75. ISF and THX certification, motorized lens cover, higher contrast, more in depth auto- calibration options and a few others where the deciding factors. That all being said, if my HD-950 did not die, I would have not even considered upgrading until the new HDMI spec and 4k/UHD was all sorted and content was available. Perhaps the lower price tag on the X55 is a good thing, and will tide you over until the new gear hits and content for them. All questions only you can answer for yourself.


Cheers!

Seeing how well the lamp is holding out on my X35 I would take the X75 too if it was up to me. I've barely lost any output after 150 hours so I'm still able to run at -15 aperture for 16:9 content and still achieve 15-16fL The extra contrast of the X90 could be lost if the iris has to be opened up more than the X75 in the same installation, plus the lamp is slightly brighter to start with anyway IIUIC.


I'll be interested to hear if you stick with using the lens: I debated selling my Isco II and getting the X55 rather than the X35 plus my lens (I already have a Lumagen for CMS and a Darbee), but the three (zoomed) X55s I've seen don't seem as sharp as my long throw X35 plus lens.

Not really. The increased contrast could be completely unnoticed if not in the perfect room. As far as the hand picked components go, I am not sure if the lens is better. So you could still easily end up with CA and uniformity issues. I don't see the extra couple grand being worth it. I would rather spend the cash on a lumagen, Darbee and or some calibration equipment.

The lumagen is a video processor that allows for many interesting calibration techniques and the darbee is another processor that adds depth info to the image. Both are inline HDMI devices, so are added to the chain. Not sure about your setup, but if you have a lumagen it has two HDMI outputs so you could run one HDMI to your amp and one to your X75.


Some links to product.

so the zoom wasnt as clear with the lens

Seemed to be the case for my set up anyway compared to zoomed X55s I've seen (3 now).

does the lumagen and darbee work together or one or the other.


Does that mean you bypass the marantz 7005

I use a Lumagen>HDMI splitter>Darbee>Projector.


This way I get to use the calibration controls on my TVs and projector (via the splitter) and the projector benefits from the Darbee effect (since I can't see any difference on my TV as it's a 40" screen from a long way back).


Having recently tried to do a quick calibration of an X55, personally I'd rate X35 plus Lumagen Mini3D plus Darbee as a better buy than an X55, in the UK you could even add an i1 Display Pro sensor and Chromapure (autocal) and still have spent less than an X55. I know that in the US the price difference between RS46 and RS48/4810 wouldn't allow this so it's a different scenario.
