They are way to noisy in this actual class D market. Purify and Hypex amps with similar power numbers and price have way less noise. Pascal modules can do a lot better than this when used right. But here there is clearly something wrong with the implementation.
 
Realistically I could sacrifice 2 out of 10,000 parts of my output to distortion and noise and I doubt anyone would be the wiser. I would care more about D-Sonic’s reputation for reliability and service.
 
So it's a subwoofer amp. Or basically a Behringer iNuke NX6000D that costs more, has about half the power, doesn't do 20Hz [edit: on program material, it probably does--the power sweep at 20Hz is not a real world test, depending on the test duration], and doesn't have available DSP. On the plus side, it doesn't need a fan mod. Got it. Yawn. Buy an NX6000, swap the fans, and get 2 channels for $390 (+$40 for new fans) with the current wildly discounted price, or add $60 and get DSP. I'm tempted to get another one just in case mine ever breaks.

Just heard of this thing for the first time: 2x3000 with DSP for $449?

What's the catch?

Isn't one, if you understand how it works and what you're getting. It doesn't do 2x3000 at all. It does less. 2000 maybe? Obviously, not continuously. But also note for just 1/1000th of a second. Few seconds or maybe just a second, probably. Obviously, amps like this are relying on the capacitors to supply power for short bursts. The 15A wall socket can't provide thousands of watts of output from an amplifier. Find the Youtube video on the NU6000 hooked to an amp dyno for real power. On program material, yes, you get crazy power for $400. With a nice side helping of distortion and possible noise. Kinda like the amp that was reviewed! I use it on subs, but I wouldn't be entirely surprised if the distortion was inaudible. Not sure what the SNR is, though. You also need to strip out the fans and replace with slower Noctua fans. They're loud. Lots of threads at other forums about this.

Thank you,

very helpful response. Will keep an eye out for the thing if I ever get a passive subwoofer (or start a band).

And in Europe, it is not worth this price but rather 700-800 euros when it is available.

So this thing...
- Has a boatload of peak power
- But doesn't match it's rated spec because
- Distortion is high, and residual noise is high
- Features (in my visual opinion also) inadequate heat sinking
Is that correct? And the alternatives like cheap Crown and Behringer are noisy in the audio signal and from their fans?
--> I think we are still waiting for something with really high power and truly "good" and inexpensive?
And likewise still waiting for a high-powered 3-channel that's not ≥$1000?
