How long does Class A have?

@clearthinker  
Yeh, Greta and her type want you and your type to be around in 100 years. Can't imagine what her motives are.

Sorry old farts, Greta will have nothing to do with the obsolescence of your class A amps. Guys like Roberto Guerra, Bruno Putzeys and Merrill Wettasinghe are the ones you should be watching. They are designing amps that sound as good, operate much cooler and cost sometimes cheaper. It’s only a matter of time before class A joins the group of nostalgic products that are relegated to museums as I am sure your sons and daughters will not want anything to do with your class A amps in their modern homes.  So to answer your question, give or take 10 years.  Yes, vinyl will outlast them. 

Philosophically, I couldn't be further from rocray...I admire GT and worry about the future.  At 70 y/o, I won't see it go completely to sh*t, but in the meanwhile I think motorsports are an affront to the atmospere and we should just stop.  We as a species should be expending much more of our energy on combating the planetary degradation we have caused.  We each can decide if we want to continue burning energy as profigately as a class A amp requires, but like the COVID vaccine, when "personal choice" butts up against societal well-being, at some point your choice costs me, despite my choice to decline...when I have to breath smoke-filled air or endure crazy extreme weather events.

I was unaware of Thorium fuel...that is exciting.  Thanks perkri for that link.

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
