Why Don't We See More High Current Electronics?

Hack, remember that a high current amp will decrease power into higher loads. There are limitations in either case. Choose your speakers and amplify them appropriately.

I just did a quick search to see what amps double down and found the following do , Ayre , Classe , Edge ,luxman , Marantz , Simaudio , Tenor and some Levinson and Parasound , probably lots of others . As others above have said I don't think that aspect is very important , even in a large room and at lease braking levels .

Well, I'm of the opinion that it matters based on what I've experienced in my system using speakers that had an uneven impedance curve.

Relating back to what Unsound stated in his previous post, the reduced power output into higher loads (lower impedances if I'm reading Unsound correctly) from an amp that does not double down (double power as impedance is halved) resulted in a sound that was always "bright" because less power was being delivered by into the mids and bass frequencies than the treble frequencies. Therefore, there was a higher decibel level in the highs than in the mids and bass. The difference was not large, and it probably wasn't noticeably measurable on a Radio Shack decibel meter, but the results were clearly audible on my speakers that had an uneven impedance curve.

Once I drove them with an amp that doubled down, the sound was evened out and the speakers no longer sounded "bright".

FWIW...

So far the efficient Class D amps I've tried have not presented the clarity, bass weight, and refinement with the (somewhat difficult load) speakers I own now. (I need some power and current damn it!). So I continue to look at Class AB designs. But I'm not interested in a 125 lb behemoth either; just a reasonably priced high current amp(less than 3k ) that doesn't take 2 people to lift and isn't old as the hills and in line to be re-capped soon. An amp with good sonics too.

You'll find that the best high current amps (tube or solid state) have the largest transformers, and are therefore heavy. The higher the power output the heavier the amp. There's really no way to escape it.
