Atma-Sphere Class D… Amazing

Well, I just put in my order for a pair of Atmasphere Monoblocks.

I was not considering Class D amps, but when Ralph embarked on this new path, I have been very interested in giving them a try.

And, as many know, I am a Vandersteen guy, so owning a Time and Phase Correct speaker meant using a Zero Feedback amp for optimal results.

Atma's new Class D amps use feedback, but Ralph believes that Class D allows for more Gain Balance Feedback that conventional amp do, and without the negative effect of adding high ordered harmonics.

(I hope I got this right Ralph...)

Indeed it would be nice to see the freq response versus load, the distortion spectra, etc....Too bad this info hasn't been forthcoming. Not sure how to interpret that...

@kuribo negative innuendo may not be a good strategy for it.

It's not a strategy, it's an observation.

So yes, Class D is more accurately referred to as a "switching amplifier" rather than a "digital amplifier" but things get blurred when binary quantization is involved as binary quantization is at the heart of digital too. 

@fsonicsmith The on and off states of a digital word have meaning- IOW the arrangement of the bits create a word which represents a voltage. In a class D amplifier the on and off states have no such meaning. When the term 'digital' is used, its assumed to not be analog. Despite being a switching technology, a class D amplifier's functionality is entirely analog. 

There's no intention to 'cut you down' or anything like that! Whenever I see anyone use the term 'digital amplifier' while referring to a class D amp, I feel its important to clarify since this is such a common misconception (or misuse of terms). If you do a search, you'll find I've done this on this site dozens of times over the last several years; please don't take it personally.

ralph, you are just a prince, you are kind, you have endless patience

kudos to you
