A very respected electronics engineer once tested many different amplifiers. Here's what he had to say about one of them.

"Very powerful and good performance with very low distortion even at maximum power"

"All in all, a very sturdy amplifier exhibiting low distortion, plenty of power, and excellent behavior at clipping. The photos below show a selection of output signals; all frequencies and load impedance's yielded similar performance"

Can anyone guess which amplifier he was talking about.

No need to guess as the reviews still there for all to see. It was when Lewis Abel tested the Void Infinite 8 Mk2.
Well known to be a chunky powerhouse of an amp.
Cheers, Chris.

If the Powersoft X4 is been tested with a restive load then one thing will be neglected. The poweroft class-D's regenerate the power supply from the back EMF generated by inductive speaker, this will happen most effectively on subs as the inductance would be very high at the speaker box resonance.

I understand that this would mean in real world the amp could sustain high output for much longer.

What do the electronic experts think of this?

Not sure I need to any more, just did 24 hours a day non stop full pelt for 5 days and no sweat broken. Subs were easily louder than full clipped 12x WSX on PKN, both up close and at distance. Was easily measuring 120dBA slow at 1m away.

Oh and they didn't go into a funny protect mode at any point



Again real world power is maybe different to what people measure on resistive load?

"Again real world power is maybe different to what people measure on resistive load?"

Or real world muzak is not as severe as a pure sine wave. Then add in the fact that speakers are a complex load, so your estimated 4 ohms, in reality, is more likely to be a bit higher. So amp isn´t actually working as hard as in a dummy load test, which is why the 'standard' resistive test is a good indication of how the amp works under stress and will separate the men from the boys.

People are talking about distortion as if there aren't hundreds of racks of lightweights every weekend clipping up and producing a distorted sound! When companies were touring with BGW Crest crown every gig was every event was just distortion ??? To me it seems like marketing/scaremongering tactics in order for everybody to buy lightweights. How much of the high end hifi market is lightweight if the quality is so superior? Or are those hifi amplifiers distortion too?

Properly* constructed Class-D (or variants of switching type of conversion) recycles some part of the reactive energy. Likely reduce that power pulled out from the mains.

Reactive energy creates extra losses in conventional (linear class AB, class-H), further increase the losses&heat + power pulled out from the mains.

There are HUGE differences between various Class-D amplifiers even from the same brand.

The new Powersoft X collapses under heavy load like music materials with high crest factors. This thing is simply not made to deliver high crest factor tones. However it may be brilliant for low duty cycle operations where sustained power levels are 12dB or less lower of the peak factor..

Otherwise the older Powersoft K10 has much higher sustained power capability than the X4. Even only two of the channels driven on the X4. Just check it with some heavy test tones, we did it.

A wise post, but its never been about what you use. Its how you use it and who you are. I've heard your sound and its good because you care and know how to please. Your selection is good and tailored for your system. Because you want to impress, give a good time and say F off to your competition. That makes you pick the right things for how you work.

That's what I was getting at. How many people have looked at an impedance vs frequency plot of their boxes, DIY or pro, and verified it themselves? At what input power? How about thermal compression?

So many people making bold statements when they probably haven't got a clue what power any of their amps are actually putting out at any moment

I completely understand and I respect how well it works for you. Yes for the pro world needs to look at impedance vs frequency plots and all the rest.

For the sound guy who wants to just go out there and give a good time to his audience, seat of the pants feeling and gut reaction is good enough.

All of this tells me you need hi tech analysis to decide whether your sound is good enough.

Time to drop the OCD and start having fun....
