The Future of Audio Amplification

Class D manufacturers, big and boutique, have years of experience / dollars tied-up in this technology. They are 'here' to make money. They won't chase a doomed topology this deep into the proverbial rabbit-hole. For now Class D makes dollars and cents, until something else comes along. And when it does, I'll be checking it out too.

Plasma TV has a tube like sensitivity in warmth, color and engaging the viewer. I’ve moved on to top of the line LCD TVs with higher resolution and brightness, a solid state like sensitivity. OLED TV is similar to a combination of the two prior technologies.   

Each type has its own limitations (LCD-picture uniformity, viewing angle, OLED-brightness in white scenes, motion judder Plasma-heat , resolution).

Yes, .02% at 1 watt is completely insane when it's all high order garbage like class D makes. Go look at the measurements. It's a very different story when .02% is this pretty, negative phase, entirely second order waveform. The human ear doesn't perceive that as distortion or dynamics like it does with high, odd order distortion. It tends to perceive it as depth. It's not technically difficult to build an amp that gets .001% distortion across the power band. It's generally thought those amps sound cold and analytical. The things that really define the character of an amp are the response curves of the gain devices and the character of the distortion they produce when driving a load. Folks aren't going nuts about triodes for their efficiency, gain, and low distortion. People love those things for their distortion and that awesome depth and spaciousness you only get from triodes and single ended JFET amps, and you only get that with that sexy, negative phase, low even order distortion. 

kosst,
Yeah. Look at some of the tube amps that have been recently reviewed with claimed output of 60 to 100 watts per channel and deliver 2 or three watts at best at 10% distortion!!!! And you crap all over class D amps. Give us a break, PLEASE!
