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?

Facebook and Twitter are NOT media companies like newspapers. They’ve successfully fought off being legally recognized as such or they’d be held accountable for the tons of lies they allow to pollute our society.

I think a lot of audiophiles who’ve been so aggrieved by this thread can be summed up as this:

Be proud about it. Own it. You’ve earned it.

All the best,

Well if you did it in my house be assured you would get the boot.  Cheers!
I'm thinking I may have to add two more pass XA's to my rig, ya know just for the tweeters :)  Long live class A. Nothing like 'em.

It is clear that folks love their Class A amps and are willing to pay what ever price to keep them, nothing wrong with that.
Greta's father works for the United Nations who works for no one. They are promoting the idea that global warming is real and needs to be addressed immediately when in fact the Earth has naturally gone through cooling and warming trends over thousands of years. They want to take away fossil fuels (which they blame on global warming) and turn us back to the stone age. They kept from us green energy (free energy) that would of made a difference in many peoples lives. Finally and more importantly they want to do a carbon tax on fossil fuels which stands to make them billions of dollars. Just my opinion.
