Geez Mark, I hope people don't love their projectors like they would a pet. That is all a bit too sad for me!
In response to Dylan, I just want to correct a factual inaccuracy in what you said. You said, the higher models are just hand picked component versions of the budget model. The ONLY model with hand picked parts is the top one. We have had discussions on forums before about the value/return of such a model because the price differential is significant and the law of diminishing returns is ever present.
In previous years where there have been three models, e.g. X30, X70, X90, the X70 is actually the one that would have had the highest expectations of a purchaser. The X30 is so good value that even if its not perfect, you would forgive it because of its price. Although there are some budding enthusiasts on this forum, I am told that X90s have found their way into swimming pools, or into houses with totally inappropriate rooms where the purchase simply wants the best but has no idea what to do with it. A lot of X90s never ever get calibrated. The X70 however is almost always purchased by an enthusiast and comes under the closest scrutiny. The X70 did not have handpicked parts. But it had significant additional hardware. It had the dual aperture mechanism, it had e-shift, xenon bulb simulation (extra electronically inserted filter), and many more software options like the CMS). It also added VGA and a motorised lens door as well as certifications like THX. Primarily because of the new aperture mechanism the X70 had superior contrast although the panels were slightly better to start with.
This year JVC introduced a fourth model which became the new home for the enthusiast. The separation between the X55 and X75 made the value proposition of the X75 a little less clear. The X55 was an X35 with e-shift and CMS. The X75 retained its differential with dual aperture, xenon bulb simulation, motorized lens door and slightly better panels. Additionally this year they added auto-calibration to the X75. But the pricepoint of the X75 meant that most enthusiasts chose the X55,
Kris, I think its fair to say you got lucky with your projector. You know very well that there is a huge variance between units from both JVC and Sony. You tested an X95 and found your X75 had better convergence for example. My X75 has good convergence. It also has good pixel focus in the centre, but not so strong towards the lower side where it becomes softer particularly in red (use the built-in convergence test screen with all the colours separated, don't just evaluate green). I do run at shortest throw, but the X70 I had before it had better focus uniformity in exactly the same position. However, as the X75 is pin sharp for the central screen area, I never notice the discrepancy. The X75 has superb greyfield uniformity whereas the X70 was not s good....and the X70 had poor convergence. It is because they are NOT hand selected in any way, that the variance is significant. My X75 also exceeds its stated spec for contrast which was the biggest surprise.
An X75 sells for 6500 UK pounds street price. The Sony VW500 is expected to sell street for 8500. That's 30% more expensive.
