Atma-Sphere Class D… Amazing

I am still waiting to see the measurements of this amp. Have they been published yet?

Whether or not it "outperforms" other class d amps can only be judged by the specs. Comments otherwise are purely subjective opinion which have no factual basis.

Personally, I commend the designer for producing his own design. So many just take oem modules and stuff them in a box.

I will say though that I will be greatly surprised if they perform anywhere near the products designed for Hypex and Purifi by Bruno Putzeys who has been designing state of the art class d amps for over 25 years and holds numerous patents.

When one can buy a complete 2 channel Purifi amp for $1000, one also needs to wonder about the cost of these amps in comparison to those made by Hypex and Purifi. I doubt they perform 5 times better and even if they did, the distortion of the Purifi is already below the audible threshold for most people. Why pay 5x the money for something you can’t hear?　Of course they may have a distortion profile that some find enjoyable, but that is a matter of taste, not pure performance.

Another spec sheet jockey. 

Purfi Amps and integrated shave never lasted more than 60 days in my system. 
 

I do like Nucor Class D had the Bel Canto ref 500 in my system and now one of my son at Grad School has them. He still enjoys the heck out of them.

You sound as if your mind is already made up. I don’t understand your logic, you seem critical and dismissive of actually listening and judging what one would hear. Of course it’s a subjective process. How could it not be? You purchase these audio products with the intent of using them to listen to and enjoy music.
 

How would one determine if an audio product is suitable for them if they do not listen to it? What possibly will the amplifier measurements reveal to you that exceeds the actual listening experience? I don’t follow your reasoning.

No, I am not "critical and dismissive of actually listening and judging", what I said was that there is no way to compare these amps to any others in a meaningful way when it is done on a subjective basis. Saying they "outperform" something else has no meaning to others when all it is someone’s subjective opinion. To be a valid statement of fact, it must be based on objective criteria. Seems this simple logical truth is just too much for some to handle.

One can’t argue with opinion, everyone is entitled to one. By all means listen but let's be clear- opinions are not facts. I am simply making that distinction.
