Optimal Temperature?

Does anyone know if there is an optimal room temperature for getting best results quality wise with music/sound? Obviously no one would want to sit in a room that is freezing or super-hot, so I am ruling those out even if it did make a difference, but I am curious is there is any difference per se with a room that is set around 68-degrees compared to 78-degrees.

Any thoughts?

I would think for most gear, cooler is better, just as it is with computers. As long as you don't get condensation.
