[QUOTE=gen0me] Hmm any estimate how much will have for example infinite 8 in burst?

https://www.abeltronics.co.uk/amptesting.php?z=Void_Infinite_8_mk2

Infinite 8 appears to behave well under burst testing conditions but Toastyghost hits the nail on the head with his analysis of the K20. What makes them different to the toroidal is the pfc (Power factor correction)where in a nut shell the amp will deliver its wattage regardless of voltage fluctuation which most know anyway.I own smp amps But do they deliver what it says on the can its close but NO it reminds me of the new washing machine it says it can spin at 1400rpm it can with two panty and pair of socks, once we start loading it up we have to change the settings so its considerably slower.

all measurements are burst measurements - just some people's bursts are longer than others

Very true Abletronics were about 100ms in some cases and ive seen 33 and 66 and as low as 5 and 12 also to be included which as been mentioned already is the freq at which the signal is delivered in an attempt to determine a power supply's strength and weaknesses. The difference comes in what are manufactures burst signals made of that's how it appears to me that they need to come together and decide on real world comparators to use, as oppose to the EIA standard 40ms burst @ 1khz

Those void measurements are continuous measurements. So on this k10 chart they would be just straight line exept the 2R burst for 0.1s (4158w) that later should fall to 3112)
Regret there is no thd for this burst 100ms for void.

Hmm
Why powersoft has 7500W on burst 100ms falling to 1200W and infinite 4158 falling to 3112. Its a HUGE unproportion.

I meant when hes getting out of steam

You might find that if you run an Infinite 8v2 that hard at 2 ohm loads, eventually channel 2 will need repair...

You mean its number of transistors?    
Some tests are quite tempting on its brother
1) how does abeltronics test them? Create sinus 50hz for 100ms plays on the level of clip and measure voltage on dummy load? Got from it both thd and power.
2)Limiter in void will not allow me to measure on such strong burst like k10?
It could be good for thd though.

That's not an Infinite 8v2…

Infinite 7.
What is the thd on this test for k10? It changes during test? As power changes?
