Atma-Sphere Class D… Amazing

He's running it with an iron hoof fist.

Worse, is he is using an Audioholics  video with that nasty Gene. 

3 of a perfect pair. 

Forget him , can the thread  get back on point.

I respect Ralph for so many things and count his incredible patience with kuribo here among them. But in my heart of hearts I wish he’d spend the time developing an even more affordable stereo version of these monos (hint hint) rather than using that otherwise valuable time trying to reason with a troll who can obviously never be reasoned with. Better to realize that 98% of the people here greatly respect you and your work while kuribo gets 2% on both counts so why waste your time? Again, why would a guy who puts no faith or credence in anyone’s subjective opinion (save his own) even be here where everyone looks for, values, and shares subjective opinions?  I suggest again that we just let kuribo keep typing away in his mother’s guest room or basement that he probably shares with her sewing machine and creepy dresses and ignore the useless drivel that’ll only become more useless, ridiculous, and annoying.  Easier said than done, but I think if we put our heads together we can do it.  Let’s Go!!!

Reading through the various opinions on these amps, some prefer the Weiss opamp, some the Burson, others Neurochrome, and others have said that the stock Purifi buffer is their choice. Some describe one op amp one way, another describes the same op amp another. Measurements show no differences which can be considered to be audible. They may all be "hearing" the same way, but their brains clearly do not seem to be interpreting the input in the same way. We see this same thing with cables and all the wacky tweak products- none of them can be shown in most cases (poorly designed cables, for example, would be an exception) to do much of anything, yet some people swear they turned their system up to an 11, others say they hear nothing. Previous experiences, mood, biases, go a long way to explain this perception paradox, This is why I find no real value in subjective comments regarding equipment on forums such as this.

@kuribo if the nueroshrome, purifi (etc.) opamps all measure the same, then what do you attribute people listening preference to? Or is it a psychological preference/bias?
