I currently own Krell class A (FPBc series) and McIntosh class A/B amplifiers. They rarely are moved so but when they are it’s not too big a job for myself and either my wife or a buddy (got to protect the back, but will also say they have not moved in probably four years so I would not base an amp decision on moving them). My experience within my listening space there is no substitute to the class A sound. Liquid, fast attack, articulate, responsive. Our listening room is in the basement so don’t really feel the heat issues others discuss. My wife will occasionally mention the heat during the summer so when she does I turn off the Krells and power up the McIntosh. I like the sound of both our A and A/B amps - but for our speakers and room it’s the class A that take the best prize. All that to say I’m intrigued with the advent of class D offerings - and would like to hear one. But like others - I’ve got an investment in what I have now and they all perform spectacularly.
