I've looked in to liquid nitrogen but never thought to check the temperature
of solid CO2. I haven't operated my station long enough to know what the
temperature response curve looks like for the PHEMT Pre-amp and LNA. I
doubt it would increase the gain but it would reduce amplifier noise.

It still looks like the best gain increases at this point (what I was
speaking of to Chip) are in the areas of added amplifier stages and the
availability of better semiconductors. I get too many looks from the
neighbors to consider increasing the size of my dish. Although I am looking
at some land in northern Indiana complete with 40 foot dish (estimate, we're
still talking, they don't really know and don't seem to care) and building.
My wife just wants the land and the trees. Sounded like a nice win-win
situation to me.
