The observation I would make having read much of this thread and based on what Ron has written to me, he likes to gather the opinions of various experts, and then based on his own thoughts pick and choose from the advice he gets. He did this with his acoustician and DDK regarding room treatment and construction, and with his electrician and DDK regarding power delivery. It is also demonstrated by his practice of mixing and matching and choosing different electronic components.
I think Ron is the chef at his Audio café, choosing his own ingredients, and presenting a menu. It’s a very individual hobby and I understand his approach. It is somewhat unusual, but certainly not unique.
