Do I esentially have a class A amp?

Kijanki,
Bravo! What you wrote has been confirmed by many who simply use their
ears. Those supposedly impressive specifications made possible with
increasing NFB don't result in high quality sound IMO.

Charles1dad, Thank you. Atmasphere mentioned negative effects of NFB many times. I still believe that shallow NFB can be used but design has to start with good circuit and quality components. The best is perhaps not to even think of it and just to listen.

I believe that most of us would agree that after a given point; a specific specs numbers can become irrelevant, academic, out of context or just marketing tools. On the other the other side of that given point; specific specs numbers can indicate appropriate or inappropriate system matching or just plain inferior design, manufacture or current operating status. And (the relevancy of) those given points of those specific spec numbers can change as the other spec points in the equation change. Before stating things as absolutes, I suggest we remember the context of the specific specs in the overall equation, when we can, and be mindful not to throw the baby out with the bathwater.

Unsound,
Unquestionably measurements and specifications have their vital place and are needed for the reasons you state. What Kijanki and others recognize is the inadequacies of measurements to determine the most important aspect of audio components, their sound. Ironically the better some specifications become, the perceived sound quality diminishes, the converse has also been observed.

While I don't believe specs can demonstrate all the qualities of sound that a component will provide, specs can offer a glimpse of what sound might be produced, especially when the specs of the surrounding components are known as well.
