It could get as hot a a one kilowatt heater too, which might be nice in cold climates but anywhere warm you would need to add in the cost of air conditioning too. So as a Devialet is one of the very few amplifiers to sound as good as pure class A, it could be considered an environmental triumph!
Yes, but the Devialet is only a 5wpc class-A amp and thus a very poor space heater.
Luckily ADH actually works so we can get most of the sonic benefits of a class-A amp with most of the power efficiency of class-D. In fact, as I noted the Devialet is more power efficient than my other class-D amp, using less energy for more power output and far better sound. We should also note that Devialet has lowered the power consumption with firmware updates, and I hope that at some point they will figure out how to power off the class-A amp in standby mode thus lowering standby energy use to modern levels (less than 1W).
