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

I'm pretty sure everybody here has concluded you're a fraud. I think the Stereophile article summed it up best. That cracks me up because I hadn't seen it before I said I'd eat my short the day they reviewed your gear. Looks like my shorts are quite safe. 
Just so I understand, you built your first amp in 1969, right? And in 48 years you haven't achieved any success or praise for your audio expertise, but you're about to teach the true greats in the field some big lessons, eh? Do you know how delusional that sounds? Stop doing this to yourself. We all see you have no clothes. Have the dignity to hide your shame.

"Nobody has to prove anything. Duh!"
Hardly a stunning statement from the inventor of the Clever Little Clock and Codename Blue Meanies. 

Costco, you are a wannabe who hasn’t done anything. Little boy, little stick, big mouth.

Big talk from the king of all snake oil sellers. You really should try working with Roger.

You’re not the first wannabe that tried to hump my leg. Go ahead, knock yourself out. 🐩
