Are future improvements in Amp/PreAmps slowing to a crawl?

You two just restored my faith in humanity..

Roger - I love your focus and energy. Hope to hear your tech one day.

Kosst - good luck. Protecting one's children has a visceral immediacy that tenders everything else moot. 
toddverrone,

Saw your system - nice. You made all the cables yourself?  And the DIY resonators?

BTW - Your listening room is way too clean! 
Nice find, Dave!

I wonder if we'll see that circuit in a headphone amp? :)

Best,

E
