Atma-Sphere Class D… Amazing

@ghasley 

+10 hopefully we can get back to the amps and not BS….  Opinions are just that. Opinions. And everything in Audio is subjective. But when so many that have heard the amps actually…. Have nothing bad to say about them. I have only heard great things from other owners. And people that have heard them at other venues.

Indeed. Its your thread and for someone to question Ralph’s engineering and design chops from left field is questionable. Glad you started it and I’ve never seen anyone question Ralph’s design choices. Atmasphere may or may not be someone’s preference but it absolutely exceptionally well made and designed. Best.

The problem with those who are certain they know the “secret” to something is the fact that they just can’t stand keeping it to themselves.

Beautifully put.

I really don’t care what others think of the sound of these amps, regardless of how many owners praise them- there are probably billions of people who love ketchup and yet I am not a fan.

I would like to learn more about the engineering and design of these amps. It has been said that there was a patent awarded for some aspect of the design- I would like to know more about exactly what was patented. I would like to see the measurements and wonder why they haven’t been published yet when this product has been years in the making- it takes very little time to upload a few files. I would like to hear the designer’s take on how his class d design differs from those of Hypex and Purifi and at 3 to 4 times the price, what they offer over the Hypex and Purifi products that makes them worth the considerable difference. I would like to know why he decided to design his own class d modules, especially in light of the fact that it is no trivial matter and a completely different task than designing a tube amp....I would like to know why the designer choose GaNfets over standard fets and what advantages he believes they offer at his operating frequency over standard fets....

    You can look up the patent pretty easily. And I would say from a consumer that has had most of those amps in my own system. They quality of the Sonic Characters (soundstage, details, realism, engaging, not bright or harsh, transparency etc) puts them above all others I’ve had in my system. If you read up some posts you’ll see the class d as well as others I’ve owned or had in my system for demo. I have not found any Class D that I liked till these came along. JMHO…
