I've mainly been updating the progress over at the Cult of the Infinitely Baffled.
I finished the electrical finally - 4 new circuits in the panel all custom wired for the theater (lighting, projector, gear, PC, and 2 dedicated for the power amps - 2400w for the sub, 500wx2 and 250wx2 for the main channels).
The screen is done (leaning against front wall) so the next step is to treat the walls acoustically with 2" rigid fibreglass, batting and something like GOM fabric. Then it's just the various finishing bits and the room will be done (hurray!).
