Its an intriguing phenomena to me.
For static captures, and [mainly] using null testing as the basis, there is no argument its NAM, followed very closely by Tonex and then the others ... done ... period.
What does discombobulate me :) [I love that word] is that until the advent of NAM, there were, and still are, '000's of video's of real amp vs KPA Profile comparisons where the overwhelming majority of people - from pros to novices - some with very good ears - who simply could/can not consistently or reliably tell them apart from a sound or feel perspective.
So were they all wrong ? Bad ears ? Lying ? Shilling ? etc.... the advent of NAM did not and does not re-write this history.
Yet, to me, since NAM, there seems to be almost an attempt to re-write this history as if it was-is somehow all "wrong" / "misguided" for want of better words.
And then this
13 year old video always springs to mind.
I find it very hard to reconcile these things.
Just a 2c thought.
