Cool, Compact, Quiet: choose any TWO.

Cool, compact, headphones.

And my choice would be: High efficiency amplifier. Cool, compact, AND quiet. Plus a lower power consumption. More complex, though, but I'm willing to accept that.

Meanwhile my alternative choice (project begun a few years ago, currently shelved) is a water-cooled amplifier, with a 20 liter water tank under the operating desk. Cool, compact (at least on the desk, while under the desk I have lots of space), almost totally silent (water pump is immersed in the water), and simple. Not so practical for contesters or other long haul operators though, because they would need to replace the water every few hours, or use a rather large tank.

Each choice has some downsides, but we do have choices. At least in theory.
