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?

Mapman, letting the heat coming off amplifiers escape to the outdoors can be extremely effective. Whether that requires ductwork depends upon the construction and what systems are in place. In other words if you are able to remove the heat there is no need to cool it, but you will need to make up the volume of air removed somehow.

My room with the big Sound Labs is pretty large. The Atma-Sphere MA-1s or MA-2s are perhaps fifteen feet away from the listening area, so the heat has some distance to travel, in which it blends with the room air. Although it is noticeable it's not bad. The HVAC system is generously oversized, so even with the big amps going and a dozen people listening, it's all good.

Mcbuddah, since you're in Wisconsin you might want to stop by one day for a visit. I have the M-60s in the downstairs system (essentially the system we showed at AXPONA a few weeks ago) in the much smaller room, and it's a very liveable, cozy and relaxed listening room.
