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?

Saw the price of the amps; let me just say I'm not bothering with an audition.:-)

Higher efficiency class d amps up the ante in terms of power available when needed. Very "green" as well.

Tube amp freaks are mostly not in this discussion as few bother with the extreme high horsepower versions as they just generate too much heat...the ones who do bother with those must have great ventilation or no clothing. Class D ain't going away, but might be kicked around by Class G or whatever's next among the switching amp crowd. I own a Class D bass amp (Ampeg PF) that sounds fine, so at least I'm on board the train so to speak.

lass g is older technology. I had a hitachi sr 804 once. Nice piece but pretty average sound.

Class. D is much more sophisticated modern technology that makes sense to me. When I read about class g it does not sound like such a great idea anymore.

I'd be more interested in tube amps if class d did not turn out to float my boat so well. Class d offers some good attributes of both ss and tube sound.

Two extreme ways to go these days it seems to me. More efficient amps to get the most out of popular smaller less efficient speakers or power hungry low output tube amps with very large efficient speakers. At least if we are talking full range in larger rooms.
