for the optical path info, he wrote the following:
"The development of optical components brings the first surprise: Contrary to expectations, no completely new path was constructed for the world's first LED projector, but a conventional single-chip light engine used. This is a well-known model: the optical path is almost identical to that of a planar PD8130 / 8150t
"Even if it is a new lighting source, LEDs, so they also can not work miracles. The native contrast is still influenced by the DLP light engine itself, and this is surprising conservative UHP and identical to that of a projector. Accordingly, "normal" behaves the native contrast to approximately 2800:1
contrast he comes in perfectly calibrated color temperature."
I'm curious to measure the other gamut settings on the 81xx to see if there are any that are consistently wider than the R709 setting (with decent saturation tracking).
price he paid = awesome, should have got it myself. 17K MSRP, not so much.
