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

PS: I did look longingly at the KAS pair that a guy in Melbourne advertises from time to time. Beautiful. Logistics though. Re your amps, KRS 200 was the original Class A version and the S was their sustained plateau bias model, yes?

Really, this is a thing? I've been running Class A for years and it really hasn't had any noticeable impact on my home energy consumption over other amp classes or tubes. I'm currently run a Pioneer M22 which is 30wpc pure Class A and it would take a heck of a lot for me to move away from it. Each to their own though.

Pass Aleph 1.2 Pure Class A 150wpc monos and will never get rid of them.

@clearthinker Have you heard the new KRELL XD 'Class A' amps?

@yyzsantabarbara     No I haven't.  I am not looking much for upgrades any more and I don't go out listening to new kit.  After nearly 60 years, I'm in the lucky position that I love my system the way it is.  I occasionally buy a phono cart, mainly top-end Ortofon.  I changed my pre-amps 4 years ago from old Audio Research to vdH The Grail and Audio Research Ref 6.  Otherwise it's all old stuff.

I read Krell Solo 575 Mono Power Amplifier 575 Watt Amplifier features 'iBias'.  This is said 'to deliver the rich musicality of Class A amplifiers, the uncompromised dynamics of classic Krell amplifiers, and the efficiency and low power consumption of Class G and H amplifiers.'  Sorry.  I don't believe you can get something for nothing.  In their publicity Krell extol the virtues of Class A and pretend they are still building it.  Neither do I trust Krell since the D'Agostinos were fired.  The way that was done suggests the new owners are bad guys not to be trusted.

In 2015 they cost $22,500/pair.  Not a lot, in the context.  Fremer's 2015 review was 'equivocal', although Atkinson found it measured 'impressively'.  For those that are concerned, the power supply isn't stiff; output doesn't double up down to 4 ohms, let alone 2.
