Do I esentially have a class A amp?

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.

My amp Sunfire 300 clearly demonstrates sound qualities per specified. It does use deep 22db NFB as most digital amps do. I can't tell exactly how many AB comparisons had been done so far swapping one amp vs. mine to just simply tell you that my amp was acquired according to specks that matched my other components and speakers and no other amp so far was able to proof its worthiness for the value. For JC sake how in the world can you beat $<1000 used 300wpc/8Ohm of continuous power stable to .5Ohm???.

Read more about audiophoolishness over the internet and do not buy neither digital amps or any other amps with NFB so they can be sold cheaper.

I don't design audio but it would be quite easy to design an amp that would measure THD=0.001% IMD=0.001% BW=500kHz and DF=1000 with absolutely horrible sound. I suspect that if you find amp like that (plenty of them in 70s) IT WILL have horrible sound (and they had). Again, spects have nothing to do with the sound. Even power spects are so vague that amp listed as one with higher power might actually play softer. Price of the amp might be even better indicator of quality than spects.

Czarivey, 22dB is not a deep feedback. Most of digital amps don't use deep NFB because there is no need for that. PWM is quite linear while output has by definition low impedance to start with (since one Mosfet is always conducting to low impedance point - GND or VCC).

^Maybe this proves your point:

Then again, maybe not.
