Cockpit Audio wiring (hyjacked from "gear warning")

I get really annoyed with endless "vario reports". Everybody in the air
probably already knows the typical thermal strengths and, if they aren't
playing with the radio, they've probably already cored a better thermal.
If you want to play with radios, get a HAM license.

The only disadvantage of this idea that I can see is that you loose the
vario sound if you turn the radio off or down to get rid of annoying
chatter.

For that reason alone I prefer the idea of a separate audio amp with
inputs for the radio and vario (and warning horns?).

Any ideas on where to get one?
