I looked at it pretty extensively and have significant capability in that area as well. I have been in major post production houses like Sony and Todd-AO and also work for professionals at their home and work who produce films for Delux, Sony, ILM, IMAX.... I have about $40,000 of test gear and custom engineered tools as well that deliver the best results possible.
There are negatives to this product. That is why it is an enhancement I would not use on my Pioneer Elite. The tradeoffs are worth it to me on my JVC projector.
Anything that alters the image going to the display is not providing the source as it was sent to you. What this can do with some projectors is restore some of the lost edge sharpness with little negative impact. Using this with other products with high MTF or using high levels of enhancement will alter the image sent to you. This can be a negative or a positive depending on your desire.
It does not add halos as found with other sharpening tools, but it does alter the image around regions where edges are found to various degrees. The higher the setting chosen the area affected around each edge is increased and the greater the change in signal levels used to increase the contrast. This can dramatically alter the image or more subtly depending on the level chosen. It can also increase the appearance of compression artifacts to various degrees depending on the level of enhancement chosen. From what I saw a low level of enhancement made the image on a JVC projector look about as sharp as a 3 chip DLP without any more increase in image artifacts than that sharper machine would have at showing them in the first place.
