OK, so you have changed your position to the extent that you now acknowledge that not all audible audio qualities are objectively measurable by your frequency analyzer.

I guess I have enough different systems, and have done enough swapping of components to know that they do not sound the same. Subtle effects are however ... subtle and sometimes it takes a while to determine whether or not you like the swapped component or not.

Enjoy the Music. Trust your ears. Laugh at Folks Who Claim to Know it All.
