Atma-Sphere Class D… Amazing

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.

Jerryg123, Marco1, you will not be disappointed in these in the least bit. I’ve got a few hours of hardcore listening time now. But, these  are truly world class as with Ralph’s OTL’s and preamps. I’d say if you like the M-60’s or Pass XA .8 and .5 series you’ll love these. Next weekend I’ll be doing some comparing with other amps. I picked these over buying Pass Labs .8 XA series amps.  I suspect I won’t be disappointed in my decision. I think either the Pass or the Class D I can live with. It’s going to be interesting to hear them side by side,  to see if one or the other is better. I want to listen to them longer. But I can say. The neutrality and realism I am experiencing is something I have never heard with any other amp. The accuracy to be true to the instruments and vocals is down right scary. I find myself walking into my living room expecting to see the band, vocalist or musician playing the specific  instrument. And am hearing details and micro-details  on recordings that I’ve never ever heard before. They also drive easy (105db 8 ohm) and harder loads (84.5-86 db 4 ohm that dip into the 2 ohm slightly) with authority without sacrificing the realism and accuracy and details. They don’t struggle at all driving bigger harder to drive Maggie’s.  The soundstage is huge and deep, with the speakers I’ve tried them on.  Like my MA-1’s The space between instruments and the separation of all instruments on the stage is also incredible,  probably as good as my MA-1’s. I have all NOS Winged C in MA-1’s and did a ton of tube rolling for the 6SN7’s to get them where they are. And have a lifetime supply of tubes since the OTL’s are so easy on them.  Best part these are not dry,  lifeless, class d’s I’ve that I’ve heard from a few other companies of higher end amps. Definitely the best Class D I have ever heard. Possibly the best amp I’ve heard under $10,000. But I’ll reserve that for the next comparisons. Not fair to say till I’ve had them side by side.
