Keeping output transistors (BJT or MOSFET) cool can be a difficult task. The goal is to allow the heat to flow away from the device. Anything that slows down the heatflow is bad.
With that in mind, has anybody tried the high-tech heatsink compounds used in PCs? The one that comes to mind is Artic Silver II. If this is a good as they say it is, it should be able to drop the junction temperature by several degrees. For someone running a Class-A amp, this could go a long way to keeping the transistors cool. It's also a lot cheaper than a BIG heatsink.
