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?

I’d suggest not questioning or addressing kurobo on this thread… let’s keep on track for/about Ralph’s amp.

Guess we need to stop feeding the 👹
Sad that most of you realize this so late when I said that few pages ago.

I find it interesting that Ralph is predicting the eventual demise of tubed power amps. Aside from the supply chain issues and embargos with Russia I think they will be around for quite some time. Now I do like some of the newer class D amps including Ralphs. I think that the goal has been to get as close to the sound of a tubed amplifier with more efficiency and reduced cost. I recall reading an interview of that Bruno P fella and he said as much.
Wish there were more GaN integrated though. Trying to cut back on boxes.
Ralph has a winner as do Orchard and AGD.

Has supply started to catch up with demand? What is the normal wait time for these amps? Are Atma-Sphere dealers likely to have them in stock?
Thanks,
