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

The question the sheeple never ask is "WHOSE SCIENCE? They would rather trust the fake news than question it and do some research


The truth is out there

I am in possession of the new LSA Voyager GaN amp. Minor tweaks include removing the top cover (the chassis is prone to vibration) and using Nobsound like spring footers which helped tremendously with speed and clarity vs the OEM soft rubber which IMHO prevents the amp from showing its true colors (NPI). It crushed my 2 year old EVS 1200, which I raved about. Seems the switching speed is a BIG DEAL, kinda like getting a much better dac could do


I recall someone saying it blew away his Clayton class A amps with the additional benefit of not heating up his room
