Default Anyone heard of Kinergetics?

Planning on buying one from a friend but he doesn't have it set-up anymore. All I know is it is a Pure Class A design. Anyone heard anything about this brand or heard this amp? Thanks.

I am interested by Kinergetics as there was a claim for them as having no "hysteresis" distorsion. I've not found circuits or schematics related to these amps yet.

What does that mean no "hysteresis" distortion?

Hi Excetera2,
"Hysteresis" distorsion. It's a marketing term used by Kinergetics, I think. I suppose it means that a circuit having hysteresis has its operating points affected by the immediatly previous signals which has been treated, the cause may be, for example, thermal effects.

Their thing was putting all kinds of weird stuff into the feedback loop to compensate for "hysteresis." For example, you'd find a bunch of solder joints in series.

Did you hear any of these amps? Did they sound good? I don't see what the solder joints in series would do but whatever. I have never heard a pure class A amp. Do they sound similar to AB's or no? Thanks.

The idea was to compensate for the "sound" of all the solder joints. Same deal with their preamp- they had a phono cartridge (sans stylus) in the feedback loop.

I wouldn't comment about the sound, since I never had one in my own system; since the idea never caught on, I doubt that this was anything special.

K. How does Class A sound compare to Class AB stuff. Will this thing just get a lot hotter? I was either going to get the Kinergetics stuff or a B&K Ex-422 just to play some bookshelfs I built. The B&K has a lot more power, but I don't need it. I was trying to decide.

I think generalizing on that would be ill advised. There are good and bad class A amps, good and bad AB amps. The idle current is just one parameter in a complicated mix; it's like asking, "Is a soup better with more or less salt?"
