Ditching Class A Amps due to Heat - Sort of a Poll


A discussion elsewhere about the future of Class A made me wonder how true one statement really is. So the questions are...

Have you done away with your Class A Amp due to Heat concerns?

Will you be moving away from Class A Amp due to Heat concerns?

Will you never buy a Class A Amp due to Heat concerns?

I only have a class A/B unit that does Class A up to 6 watts with almost no heat so really can't speak for those who have used in the past or currently own and run Class A Amps.

Another Luxman 590AXII owner.  It's actually high bias Class A to 30 watts, then A/B to 100.  The 30 watts is enough for most everything.  That said, it's really heavy, at 65 lbs. Never gets hot to my knowledge.  It sounds like Class D is really advancing with makers like Atmasphere innovating.  When the consensus is the sound and value exceeds Class A and the products are light weight, run cool, are priced right and are better for the planet to boot, count me in.

WOW. Hard to imagine that people thinking they could find anything at twice the MSRP to be better, although, W4S has been beta testing a new kind of GaN amp that eliminates the dac. I haven't found anything about it, but...

WFS probably has the EAS GaN digital amp boards and is testing them. Digital amps are the future....all DACs, preamps, and normal amps are now officially history.....he he. If you play CDs only, the best sound will be to burn the CD (with treatments done to it) onto a hard drive and play it from a streamer or computer into the digital amp. There will be integrated fully digital amps (more advanced than Technics and Lyndorf) that will have a coax input and volume control built in so you can play a CD transport directly into them.....there will be tons of these kinds of products out. It’s only just begun.....add to this that you can bi and tri and quad amp with these things and get rid of all the crossover parts.....and you can even make your own speakers as all you need is woofer/box alignment or use open baffle and equalize (digitally). We are in for a wild fun ride.......AND when you add getting off the grid using a big Giandel Inverter and using the Puritan line filter and ground filter system with dedicated ground rod just for your stereo!?!?!?!?! OH YEAH......you will never need to go to an audio show again......Nirvana will be at home.....and affordable. You can do all of this RIGHT NOW! The Peachtree GaN 1 amps are for sale......buy two for biamping....buy three for triamping.....OMG!!!!!!!

Am I repeating myself?  The GOOD NEWS is worth repeating.

If someone is going to ditch their class A system because of heat, I guess a tube system is kicked out the door too! Really, the only drawback I can see in a class A is energy waste from heat dissipation.  Enough it may raise the electric bill. However in this forum that's not a problem .
