@williewonka "I might feel different if there was some context as to how it was derived."
Agree, more context and a better understanding of each of the parameters from the maker of the graph would be helpful and very interesting. Anything that AudioNote puts out is worth studying. Some of the best gear I’ve ever heard, anywhere, particularly if one simply likes to sit down and simply listen to music. My local dealer is mainly AN and QS, and will ask him about the graph too. @jjss49 btw, I had been observing the new Cobra integrated when it first got introduced, also wondering why the transformers are so small. Hope to hear it some day and see how the sound relates to the graph :)
