I see how I miswrote. But I'll stand by.....that as the temperatures of the room and amp get closer together, heat transfer slows.
Point is, cooler is better and you can cook it in a hot environment.
Heat and temperature are 2 different things.
And NO, the amp won't always be the same temp delta from ambient. In SS, for example, you have a max temp possible....say the junction temp of the devices. In a hot room wont' the difference drop as the room temp approaches junction temp? Or will the junction keep getting hotter until failure? Isn't there an upper limit to the temp of an amp?
2 amps of identical efficiency and power rating being run identically will be at different temps depending on the mass of the amp. And we all know how much heatsinks cost.
It's kind of an aside, but look at a few Stereophile amp tests where they 'precondition' an amp at 1/3 power for an hour before bench measurements. Some amps fail.
I'll call a friend of mine who is a PHd in physics. he'll straighten me out. His area of expertise is semiconductors, so it'll be good info.
