Why Don't We See More High Current Electronics?

Meant to write low efficiency.

Newer Class D and Icepower specifically meet the criteria, are becoming increasingly popular and are more practical for most, and may be undercutting the value of the traditional heavy, power consuming and expensive to build well monster amp, which was always a niche item to start with.

I know in my case I needed the high current, high power amp to drive my larger speakers properly and to the max. I considered Class D or traditional monster amp. I decided to go Class D and have no regrets. Every time I listen, the sound just blows me away.

In general, greater efficiency is the wave of the future. That can mean a more efficient amp to deliver the power and current needed as in Class D or more efficient speakers that require less power and perhaps also current. Either approach or even both in conjunction to some extent can greatly help bring an otherwise under performing system up to par

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.

Mapman, these newer Class D amps with their relatively inexpensive, diminutive dimensions, cool running, high current, high powered prowess just might free up speaker designers from the limitations of meeting the criterion of high efficiency speakers. The future just might be the opposite of what you predicted.
