Atma-Sphere Class D… Amazing

@kuribo 

There is no mischaracterization of your comments. You have plainly stated that Purifi and Hypex are state of the art and their measurements prove it. So again, what measurement could Atmasphere provide that would prove his amp is objectively superior to you? You have done an effective job to this point in this thread of not answering that question. If it can't or is even equal, in your opinion it is a poor value. You have stated that ad nauseum here. 

It seems that you are the one with poor reading and comprehension skills here. And it is pretty easy to see through. No conspiracy, no knee jerk reaction. Just calling a spade a spade. I will quote you one more time here.

You don't like it, that's your issue to deal with.

@jjss49   Perhaps not so weak and lame but rather the ill-considered rantings of someone who I suspect, judging by his incoherence and lack of respect for the English language, was drunk, stoned or high.  Whatever.

Exactly what is the reason that you chose to paste that rant on a thread dedicated to discussing the finer points of the Class D amp made by Ralph?

@csmgolf 

Did you bother to look at the suite of measurements published by Hypex or Purifi? Obviously not or you wouldn't keep chasing your tail asking me. Seek and ye shall find.

I have no interest in doing your homework for you. If you are too lazy to look and find the answers yourself, you don't deserve any more of my time. When you are ready to discuss the facts, let me know.


 

@kuribo It should be blatantly obvious.

No, actually. Please provide exactly what tests you wish to be performed. One at a time.

I will agree with you should you be able to be specific, rather than saying just look at the websites of Purifi and download the information provided...that is quite a rude approach to maintain.

If you desire information, it is your responsibility to request it. Politely.  I do understand that this is forum is predominately American, and I am not.
