As far as amp warmth on mine, I'm not quite as concerned, but it's still a bit warmer than I would like. It doesn't seem like it can be healthy having it that warm with no ventilation, but maybe it really is fine.

I'm going to switch the positions of the two EP800s this weekend. I put the replacement amp in the one on the wall closest to the two openings simply because it was the easiest one to access, but having it on the opposite wall will make it a lot more effective. I'll have to run the AS-EQ1 calibration again, or I might just run them straight from the Integra and skip the sub EQ until I get two fully-functional new-version EP800s. I'm sure it will be fun to really crank the new one in the better position.
