Well, I have tried some of what you claim to be The Way. Like deciding that a pentode linestage loaded with a 500 Ohm plate load worked well. A quick FFT showed why it was so dramatically different: loads of 2HD. Lots of folk went totally thumbs up over it. Those same folk got a wee bit less enthusiastic after a bit, and went 'holy smoke' when a clean, low output impedance one got plugged in.

You have developed the tone machine into an art denis, of that I have absolutely zero doubt. You are also quite good at selling them. neither of those things fall into a category I'd find valuable.

DF and the MLP have mastered the "concepts" of transfer efficiency, non-critical inductance LSES L-input PS filters, non-linear biasing, ZERO feedback beam power finals and creative use of harmonic distortion to create "realism" in high fidelity audio reproduction.

These "concepts" are beyond the scope of an EE or bench tech versed in standard tube audio theory and practice.

If we are still alive a decade or two beyond 2022, we might begin to grasp the esoteric knowledge that DF and the MLP designers have presented here and on other audio forums.

But that is perhaps being too hopeful given the overall demeanor of participants on AA Tube DIY.

  Denis has mastered a Marketing Spiel full of words that, in context mean NOTHING.
  
  In several years, we will discover they mean nothing( actually, we already know they mean nothing ). That is not going to change...LOL
  
  It is not that EE's don't 'get it', they know what it is, and want nothing to do with it, regarding it as pointless to build an effects box when faithful reproduction and True listening enjoyment is the goal.
  cheers,
