The End Of Big Iron?


.
Once upon a time you could buy a 1,000 wpc, a 900 wpc and a 750 wpc monoblock from Krell. You could buy a 1,000 wpc monoblock from Pass Labs. Now, 575 wpc is the biggest you can get from Krell and 600 wpc is the biggest you can get from Pass Labs. The muscle of flagship amps in those mfgs has been virtually halved. I mean, was 1,000 wpc, 900 wpc, or a 750 wpc amplifier ever necessary? If they were, why are they no longer necessary? What has changed in audio or speaker technology to cause the dwindling of 'muscle' amps?

Basically, I have high efficiency speakers, so Class A should be no problem.

Dave, those speakers are also an easy load for tube amps, which work quite well on them- several of our customers use similar JBLs (the export version).
Mcbuddah, what is wrong with your Atma-Sphere amps? Bad tubes?

A simple and inexpensive means of dealing with hot amplifiers, tube or solid state, is to install ceiling ventilation with ductwork to move the warmed air out of the building. This is very cheap to install and costs very little operate and is very effective! Air conditioning is rather brute-force.
