Which only costs 6k! :facepalm:

"Our bench tests of the $6K AMPED 2400 stereo amplifier, rated at 800 W per channel, show it doesn’t reach its claimed power. Featuring a proprietary AUSP™ Class A input driving a Pascal Class D output, it sounds clean and dynamic, but the build feels more like a DIY project than a premium $6K component. Is this amp worth the price and does it matter it can't hit rated power?"

AMPED 2400 800 Watt(?) Stereo Amplifier Review

Our review of the 400 watt/ch AMPED 2400 Stereo Amplifier revealed bench numbers that didn’t match the claims. It delivers clean sound, but the build feels more like a DIY project than a $6K component.
www.audioholics.com www.audioholics.com
The AMPED 2400 produced 416 watts/ch, both channels driven into 8 ohms at 1% THD+N and 328 watts/ch under similar test conditions at 0.1% THD +N. Anyone familiar with how I test amplifiers knows, I prefer amplifier manufacturers to rate power before the knee of the distortion graph which in this case would be about 280 watts/ch. The rise in distortion above 100 watts shows the linearity of power vs distortion isn’t as good as today’s best Class D or linear amps for that matter. Still, I was at least able to reproduce the manufacturers claim of 400 watts/ch into 8 ohms for this test scenario.

The AMPED 2400 did not reach its rated power during our CEA-2006 burst tests, which most closely resemble real audio program material.

If it's just Pascal amps with a froo froo input stage, I doubt it measures well. And not great to fail to hit spec when you're using off the shelf parts!
 
I thought this comment was an interesting perspective on quoting as per the FTC standards

When I reran the test for 5min at any given single tone frequency from 20Hz to 20khz, the actual output power dropped to 190 watts/ch, both channels driven per the new FTC Ruling which is about half the manufacturer’s rated power. By strict FTC standards under the new rule, this would be a 190 watt/ch amp with 3dB of headroom.
