Axiom Home Page Forums General Discussion The Water Cooler Who reviews the reviewers in the Audio Industry?

BTW, I have no idea what Axiom's test protocols are for measuring continuous and dynamic power. Out of professional curiosity, I'd love to know. I can tell you, as I've reported on these boards, I've confirmed as best as I can with my very humble equipment that continuous and dynamic specs are being achieved with the 1500-3 and 1000-3 I have here.

I'd have to check my notes to confirm but I think the 1000 has 35V rails and the 1500 has 55V rails. Those of course are +/- rails so that's 110V across both rails for the 1500.

I'll also point out Anthem spent a bazillion dollars and drove many engineers with master's degrees insane to bring the M1 to market. That 1U monoblock with an SMPS and class D amp costs 5 grand and can dump 1000W into a 4 Ohm load and double that into a 2 Ohm load with vanishingly low noise and almost unity power factor.

What it can't do is provide the 4500W of dynamic power out of a standard North American outlet that the 1500 can. The 1500 does that with a power supply I could have designed in Grade 11 and can be easily repaired.

I'm not done. LOL! Ian's brilliance is blinding because he saw through all the BS and said I'm not gonna play the continuous (RMS) power game. The money shot is dynamic power. And he knew the best way to utilize the standard wall plug was a combination of LPS and class D amp. He cut his teeth on the subwoofer amps, nearly blew himself up with the 1400 but kept going not because it was easy but because he saw the future and it was the right thing to do. Now he has these massive, multi-channel beasts with gobs of headroom to feed actives. And the actives are gonna sing like platoons of angels from heaven. Hallelujah!

Ok, back to higher rails and a storage cap ... switcher supplies continuous power, cap supply’s dynamic and all is good.

Nope. That's not how a switcher works. The most it can give you is what's in the plug less the amount it wastes.

So just buy eight 1500-8s to go with you eight 800s.

Disregard supply type. If we can source 100 watts of power continuously and store another 100 watts-seconds of power for instantaneous use how much power can one draw instantaneously?

200 Watt-seconds. Now show me an SMPS that does that.

Excellent!!
The SMPS is the continuous 100W supply ... it feeds the 100Watt-sec storage ...
when it's fully charge you have 200 Watt-seconds of instantaneous power ...
the rest is just circuitry ...

Oh ho ho ho! You will go broke.

Maybe ... but I’d get greater efficiency
And which is more the switcher or that big transformer?
