You may want to check your settings, the video doesn't play in an embed as in your message above.

Carver was especially well known for pushing snake oil, usually justified by completely redefining common terms of art. For example, the "Magnetic Field Power Amplifier" which is not, despite the name, an amplifier based on saturable reactors. He redefined "Magnetic Field Amplifier" to mean a transistor based amplifier with a switching power supply.

The problems with stereo reproduction are, in fact, mostly due to transducer limitations, so it's highly misleading to say that it is "pale and muddled, no matter how good your speakers are". Perfect speakers (without resonance, phase shift, or dispersion) produce perfect, spatially realistic sound, when the recording captures stereo information. Unfortunately, perfect speakers are also unmanufacturable, so the only way to improve the sound is to compensate for their defects in some way—and self-powered monitors are designed to do that compensation to a better or worse extent. This is simply not possible by pushing a button on an independent amplifier since it has no understanding of the parameters of the transducer in use.

Ion speakers (plasma or flame) have no resonance and perfect dispersion (except the tiny area blocked by components). http://www.swtpc.com/mholley/PopularElectronics/May1968/Flame_Amplification.htm

So yes, it is possible to build a near perfect speaker (the limit being construction), however, it would absolutely not be something you could have in your living room, or even in your house except your garage. It would take large amounts of electricity for an arc (or corona), or for flame electricity, fuel, catalyst (either solid or mist), and produce lots of exhaust.

Also, aren't Carver the ones with those stupid unregulated triac dimmer supplies that you had to plug into a line stabalizer just to even use?
