Why Don't We See More High Current Electronics?

You can get the exact same current delivery for a given load without the expense of an amp that doubles its power when the impedance is halved. It's true that such an amp, depending on its power capabilities, could accomodate a wider range of speakers, but in general it's unnecessary.

Which would you prefer, a 250 watt amp into 8 ohms that doubles into 4 ohms or a 600 watt amp into 8 ohms that produces 900 watts into 4 ohms? -03-14-11: Bob_reynolds

Errr ...ahhhh.... Hmmm.. the one that doubles thank 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.

LOL .. Deja vu Ralph ?

there are more manufacturers here in the US of vacuum tube audio products than there was in 1958! - Atmasphere

Yeah, but i wouldn't hold it against them, it's their use of carburetors that gets me... :)

Accuphase, is often overlooked, very good amplifiers...

I can't for the life of me understand those that spend thousands on an amplifier that shows current limiting and power supply issues going from 8-4 ohms.

Ahhhh bwoy ...

Because it shows a deficiency in the power supply and hence topology being used IMO, nothing to do with speakers.

Why spend thousands on an amplfier that has a mediocre PSU and Amplifiers that do so always sound unmusical IMO, same with high bias Class-A ( SS) amplifiers, they give up life for smoothness and is usually preferred by those not familiar with recordings of live music and or poor speakers.

Irvrobinson, he wants something that doubles power as you cut the load impedance in half. But I don't like feedback (human hearing perceptual rules meow meow...)

Atmasphere, technically there is no such thing as no feedback in an electrical circuit and hence a zero feedback amplifier, can you quantify your statement ?

Not a fan of the VK500 or The Belles, Threshold S500 .. Yes!

Unsound ,

I won't disagree, i can only express my involvement at many levels and again iterate that I find high Class-A Bias amplifiers not to sound like live music IMO, tending to be soft and laid back ( gentle) and nothing like the recording or live music, of course there are exceptions, but for the most part, , yes, this has been my observation.

Again speaker topology play's a big role here and of course there are those that prefer soft and gentle to
"real " and if you have a speaker which is forward sounding or "bright" it will have an issue on anything but Class-A.



Class- D have what i speak of in spades, unfortunately other issues with that topology leaves it a bit dry making ClassA/AB still the best output stage topology IMO.

Irv,

We have taken Krell's and re-biased them to 10% of their original class-a bias after service and recapping and the difference is astronomical.

Anyone with an older Krell KSa 200/300 et al series should give it a try, no more 1400 watts being pulled at Idle .
