Class D and High Efficiency Speakers?

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.
