Remember: 1. Real class A draws full current at all times.
2. They will be at best 25% efficient
3. Therefore at idle they will be putting out 4x their rated output in heat,
So if your amp is rated at 25 watts per channel then it will be putting out 200 watts at idle, less when it is driving the speakers. My experence with other Class A amps tells me that you had better check one out personaly if possible to see if the heat will be too much, I am afraid that it would be.
