Too chilly for you?Class D is most efficient because after 5 mins you Turn them off and walk away ..!
I think you might not have read my post correctly.
I'm happy with my class D amps and don't see any point in using anything else.
So why not high bias class A for everything?
This is a high fidelity amplifier class. Class A amplifier's output transistors run at full power whether there's an input signal or not. When there's no signal, the transistors' power transforms into heat. When there is a signal, the power goes out the speaker terminals.
Also, each Class A output transistor amplifies both the negative voltage and the positive voltage parts of the signal's AC waveform, increasing the workload and raising more heat. Class A amps function at a 25% efficiency level and the remaining 75% of their power is turned into heat.
There are no turn-on, turn-off, warming, or cooling cycles that would affect the signal flow. In this class, you get distortion-free performance. Besides there is no switching going on, meaning there is no induced high-frequency interference. Pure Class A amplifiers are rare and expensive.
The difference is not going to stop global warming, no.I not talk about if a 5w tube or a 5w class d is more efficient.

It’s Audiophilia we work with sights ...
Do i have to say it, we are talking absolutes not strawman every chink in armor content...
Specifically sonics.
There's my problem, all these years I've been using my ears.It’s Audiophilia we work with sights ...
The difference is not going to stop global warming, no.
However in battery powered application of many sorts, designers and indirectly users DO care about the efficiency.
Sure thats why you wont see tubes in this applications. It would be completly stupid. So still no need to talk about the efficience of 5w tube amps.You wont see tubes in BT inears.
Speaking of battery-powered, I wonder how they pack 6 hours into each earbud
(21 hour total, 6 hour earbud 15 hour case)
