OK, great to have that info!
So in the 30 to 60k range we're mostly looking at projectors that use UHP lamps in the 260-330 watt range and have the ability to output around 2000-3000 lumens for a while. Most, if not all, have the ability to do 3D.
The Display Development projectors use 500W and 1000W xenon lamps range from 2000-5000 lumens, but cannot reach contrasts like the Lumis reportedly has (max 10k:1 vs max 35k:1). The DD units do not have dynamic irises or use a dynamic black function.
There are plusses and minuses to all of them; the DD units are for people that need to shoot a huge screen and can have a separate projection room (unless you're planning on a hush box), the DPIs and the Sims are for people that need the projector in the theater and need it to be quiet.
Lots of output capability with pretty stellar image detail, xenon color reproduction, but heat and noise, and probably not the best blacks of the group- the HD5 and HD6
Small, quiet, punchy for average screens, great blacks,3D capability, but the pitfalls of UHP illumination- color drift, not as accurate color unless you notch filter (which whacks the light output) - Sim2s
Medium size, medium noise levels,3D, lots of light output choices, but UHP lamps that share the same pitfalls as above, .69" vs .95" chips, optics not up to snuff of the others- DPIs
Large, great optics, great color reproduction, DCI compliant color space,3D, also UHP lamps (see above), high price comparatively- aviello HELIOS
Large, hot, Loud, better optics than Highlites, 3D, UHP, notch filters, HC or HB optics, high price like the Helios- DPI Titans.
Obviously, I can only speak to my personal experience; my experience has been that the HD5 exceeds the capabilities of our Titan Reference and at 1/2 the price. I can only compare the general plusses and minuses to other projectors. I do know from experience that HD5>Titan line= Lumis line (different strengths to each)> Highlite line. So by that logic ; HD5 > Highlite line , probably > Lumis line (again different strengths, so that could actually go either way depending on what's important to you). I have seen aviello pjs and they all do look quite good, but without more playtime, I will not make a qualitative comparison- only that the HD5 is probably close and again half the price.
Perhaps I can convince the local rep for Sim2 to bring in a lumis for comparison- but I will not hold my breath on that, since I asked to see a Mico a year ago and haven't heard from him since.
my .02 YMMV.
