Can You Get 1,000 WPC Out Of Regular Wall Socket?

.
Map, I've never tried a class D amp before. The whole
concept of small amps delivering that kind of power is
intriguing to me. I have Carver Silver 9t monoblocs that do
an excellent job in a biamp config on the Kappa 9. They
weigh only 13 pounds each...the Pass monoblocs weight more
than 130 lbs each. The Carvers actually deliver bass with
much more authority than the Pass monoblocs. But, the
Carver amps are 20-25 years old. I need to get rid of them
before they go bad. I'm looking for some 21st century
amplification and to save some money. If this class D stuff
is all it's cracked up to be, there's nothing more than I'd
like better to do than get rid of all this "Big
Iron" and go small and efficient.

Ddd1...Hmm, no mention on the D-Sonic site on whether the
1500 wpc is sustained or for milliseconds. That really
changes the picture if it's only for milliseconds.

Al...I will make inquiries directly to D-Sonic and do some
research as you have suggested. D-Sonic has a 21-day trial
with a 10% restocking fee.

I doubt power ratings for any switching amp is "sustained", but not sure exactly how to quantify it. Al could probably do it better or maybe agoner Kijanki if he is out there (both excellent EEs).

I have heard mixed reviews with Class D amps on very difficult load speakers like the Infinity's seem to be. The devil would be in the details I suppose. My OHMs are not easy, but I suspect not as difficult either. I might go out on a limb though and say that if the Carver amps can handle it, a good Class D design with a good power supply design (not stock Icepower for example) probably would do fairly well. Again, devil in the details.

I had a 360 w/ch Carver m4.0t amp for years before recent upgrades, two amps ago, running older, larger Maggies and my OHMs. Bass WAS wall shaking prodigious on the OHMs with proper recordings, well recorded organ music, etc. Bass with my Bel Canto Ref1000m is equally impressive, but night and day, way more clean, powerful, and nuanced, though I seldom get the wall shaking effects that the old Carver gear (amp and pre-amp) used to provide. I think it has more to do with the low end rolloff of my ARC sp16 tube pre-amp compared to the old Carver pre-amp than with the amps though.

The Carver monoblocs are rated at 575 wpc @ 8 ohms and 900 wpc @ 4 ohms. I am using two monoblocs per speaker to drive the Kappa 9. One monobloc per speaker just doesn't get optimal results.
.

I see in this review of the M2-1500M a statement by D-Sonic's owner/designer that "all of our amplifiers perform per specification into sub 2-ohm impedances." That does NOT seem to me to be an encouraging sign with respect to its compatibility with the Kappa 9.

On the question of how long the rated power can be sustained, assuming that the provider of the rating is not being devious it would have to be for far longer than milliseconds, in order to comply with Federal Trade Commission requirements for amplifier power ratings. My understanding, though, is that in general Class D amplifiers cannot sustain their rated power for as long as other amplifier classes typically can. Kijanki is more knowledgeable about Class D than I am, so hopefully he will see this and chime in.
