How long does Class A have?


Hi Guys/Gals
 I have a Sugden A21SE which is a Pure Class A single ended design, I absolutely love this musical amplifier with its strangely plentiful 30wpc, it runs hots as they do, I always enjoy watching the faces of my uninitiated friends when they touch it after I mention they get hot, lol.
But in this modern green era I wonder just how long do Class A amplifiers have before Greta Thunberg gets wind of this inefficient method of creating sound and pisses on the parade?

Thoughts?

Im no climate change advocate, but electricity is getting more expensive, not less. I ve owned class A heaters, and 250w tube heaters, so there’s the added cost to cool the room.


I have been in possession of a LSA Voyager GaN amp 350/600 wpc. My previous class D is dual mono based on IcePower AS 1200 modules. The Voyager is as potent but much more dynamic; zero to 60mph is Tesla Plaid like, and yet natural sounding with a ginormous sound stage and barely warm to the touch, and a mere $3000!

Any financially frugal person looking at class A prices, but who hears the Voyager, will likely choose the latter, unless they have money to burn. GaN technology is in its infancy, and I suspect it will dominate the market, usurping class A & AB sooner than later
As long as the speaker I want needs/wants a lot of juice (Magnepan at present), I’ll likely use a Class D power amp, likely preceded by a tube or Class A front end. But I am one of those who also finds Class A has a certain appeal with high-efficiency speakers, and so I will have my First Watt/Pass (diy) amps in secondary setups. I’m on all-wind power, so I don’t feel guilty leaving it on. But I’d still feel pretty silly running a 100-watt or similar size Class A amp.
We need more Greta Thunbergs
We get too much useless hot air from politicians and political commentators as it is.

    As we die off, our heirs will throw our prized systems in the rental dumpsters.  I retrieved a lot of things my sisters threw away.  They will trash my stuff, unless I donate it to, maybe, a theater, which will quickly destroy it from ignorance.
Cheers!
