Atma-Sphere Class D… Amazing

Opinions are factual in the context here. They are factual because of the 100% subjective nature of the topic. Some just can’t handle the truth it seems. Measurements are simply data points. They have nothing to do with the reality of sonic preferences and resulting opinions.

We just have to accept the sonic preferences and experience based opinions as truth for that person. 

So IMHO, after some in depth listening today so far. I switched back to my MA-1’s. I do prefer the MA-1’s. I like the attack and decay of the MA-1’s better. I like the depth and fullness of acoustic instruments better.  It’s a warmer presentation you’d come to expect from tubes. Although I don’t believe the M-60’s would keep up to the class d. I also believe if someone likes a nice SS Amp like Pass XA 60.8 they may prefer the Class D over the MA-1’s. Also there are a few things that I do like about the Class D over the MA-1’s. To be fair though I rolled a lot of Tubes in my MA-1’s looking for a certain signature. And that’s what I am used to. And the MA-1’s I have are 4 times the cost. So I’d hope they were better. 
  With that said….. Clarity, neutrality and especially realism is where the class d shines. It definitely stays true to the music, instruments and  adds a higher level of micro-details. I hear a few more things in the class d. I am going to roll in some tubes that aren’t as soft and warm in my Ma-1’s. Anyway…. I’ll see what others have to say today and tonight. Hoping a friend can bring over his fully optioned M-60’s soon. I know when I moved up to the MA-1’s it was significant. 
 

JMHO…..

Opinions are not facts even in the context here. All you have with any 100% subjective topic is subjective belief, the only "fact" is your belief of your preference and opinion. Facts are universal not individual. 

Here's a fact.

How sound becomes hearing.

A fact is simply collected information and not universal. It is a fact that we each hear differently and own different systems in different rooms. It is a fact that we as unique human beings have varying sonic preferences. This is all accumulated information and fact. Our opinions flow from these differences.
