Why Don't We See More High Current Electronics?

Here's one more for you:

Why not ask what the relationship is between doubling power and how your ear/brain system hears? The short answer is that you get flatter frequency response, but only with certain speakers. This comes with a price- distortions that the ear is extremely sensitive to. The ear hears these distortions as a variation (coloration) in frequency response! So in a way, you can't win with the explanation of flat frequency response.

The actual fact of the matter is that if you want the equipment to sound like real music (which IMO is the goal of any high end audio system) than some of the design parameters that bring you the ability to double power as impedance is halved may have to be abandoned. So you are seeing that occur, for example there are more manufacturers here in the US of vacuum tube audio products than there was in 1958!

Jylee and Charles1dad, I couldn't disagree with you more. I have yet to hear any of these more efficient speakers that satisfied me.

unsound,

Could be.

Regardless of which approach makes more headway, more efficient amps or more efficient speakers efficiency always rules when it comes to doing more for less.

I suspect a consumer has more and perhaps also more cost effective options regarding speakers currently building around a high efficiency amp like a Class D than one does going the high efficiency speaker route, especially if one cares about good full range performance and not giving up the lowest octaves.

Mapman, that depends on what your defining as more and what your defining as less.

I suspect your suspicions are spot on.
