My god, that guy is really serious. At first I thought it was just another prank, but reading through this guy's claims, he really believes he has something there.
"I have invented, engineered and built a working prototype(1W) of a new class of analog solid state audio amplifiers that will called as Hyperbolic Amplifiers"
- Ok, so building a 1 Watt audio amp and testing it isn't really that relevant. The distortion behavior is going to be way off, compared to a 20W or 100W model (here I'm referring to the same "hyperbolic Amplifier"
sh... stuff)
"Hyperbolic Amplifier's open loop transfer function approximates a linear function and therefore negative feedback is not required. Also no hard clipping occurs when overdriven. This means spectral profile of the amplified signal consists primarily of low order harmonics."
- So... no negative feedback? Ok, that sounds (pun intended) like a recipe for disaster. Harold Black would be turning in his grave right about now. I wonder how long will one of these amps take to fry someone's 1000$ speaker set?
"The hyperbolic amplifier is extremely power efficient. For the prototype, quiescent current is 20 mA. The power efficiency (ratio of output power to drawn power from power supply as a percentage) at maximum load is 95 percent.This is comparable to that of a class D amplifier!"
- 20mA Iq for a 1 Watt amp? really? Just for giggles, a traditional 3 stage 100W audio amp using a complementary feedback pair output can have anywhere from 15mA to 30 mA Iq
"The goal is to mimic the spectral profile of a vacuum tube audio amplifier using only solid state transistors - rich in lower order harmonics but negligible to none of the higher order harmonics."
- So, after more that 40 years of research, development and innovation, where one can easily build a "blameless" amp, this guy is trying to increase the THD on purpose, just because it sounds nicer?
Ok, I want to get off this planet.
