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.
