You make an excellent point and I did consider this. In a perfect world we could conduct a direct A/B comparison. Unfortunately, for most of us we are limited to some variables.
In my comparison, the source material was identical. Same hard drive was feeding both projectors.
The screens were different, however. The Ruby was displayed on a Screen Innovations Visage which is a higher gain screen but the image size was considerably larger, the Ruby at 108", the Pearl at 92". The Pearl was displayed on a Firehawk G2, 1.2 designed to minimize ambient light reflection. The difference in the size of image should offset the difference in gain. Although the higher gain screen will allow for greater light output, it may suffer in other areas such as picture uniformity (smoothness) and contrast.
The difference in picture quality was dramatic. Not only was light output greater with the Ruby, which may be partially explained by the screen gain, although as noted offset by image size, the Ruby was as smooth and appeared to have better contrast than the Pearl. I doubt the screen variations were so different that they would explain the discrepencies. Also, one would expect a retailer to display its products in the most favourable light. It would have been interesting to see the Pearl on a Firehawk SST.
Your point, however, is well taken and should be taken into consideration when comparing any projectors.
