Class D and High Efficiency Speakers?

Johnk,
Understood.

As a retailer I have various class d amps here which I switch in and out of systems to understand the strengths and weaknesses.

They are a godsend for difficult loads when space, heat, and budget constraints exist.

And the sonic quality is becoming very very good with the proper load.

Let's not confuse snobbery with years of experience.

Of which I suggest you seem to lack.

Good luck with your Onkyo or Pioneer or Kenwood or whatever.

Thank you. I rest my case.

Johnnyb53, trust me, Audiofool, will not give it a rest. He knows all. Good luck.

The subject of class D always seems to bring on the detractor who's class D experience can be limited to varying degrees. My red flags pop up when I hear the general reference to class D and not a specific model.

While I still own a fine tube and linear solid state amplifiers I'm terribly class D biased. Class D amplifiers are far more sensitive to their physical and electrical environment than most other designs. In many cases AC line conditioning can simply make things worse. Class D is not plug and play.

Warnsy! Your own advise is the best so far, try it yourself. I did hear a system with some home made horn enclosures powered by an early version of Red Wine amplifiers and the music was stunning. I haven't followed Red Wine's progress but I'm sure they've been busy improving their design.

My personal switching amplifier advances have come from: a dedicated shielded AC Circuit, mass loading the casework, replacing a tubed preamplifier with a battery powered solid state preamp.

Of the eight class D amplifier I've had in my system and either before or after my systems upgrades I have never experienced what someone referred to as 'switching noise' from the amplifier. As I understand it the switching occurs at 50kHz and usually much higher.
