Update on the temp. I'm not sure what the difference is (maybe more mass around the Empeg) but after running the Empeg non-stop in the docking station for two consecutive days during my working hours (8 hour days) the Empeg seems to stabilize at 107 degrees F. For my initial test I used just the MDF sled (actually a early test prototype) for 4 hours, and it hit 100 degrees F and seemed to stay there. When I take the Empeg out of the docking station, it is warm but definately not hot, and most of the heat is on the bottom of the unit. My dock design just vents the two side vents out the back of the sled, I have no vent for the top.
