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

Ralph,

I love your innovative attitude as well,And greatly look forward to your class D design.

I really enjoyed the Sit2 amp but I like my Diy sit that is push pull that uses nos Sony Vfet's.How could I not.

What we need is some new transistors directly designed for audio amplifiers and not other applications.I have no Idea what that would be but I'm sure Nelson would.

Kenny.

Then, Ralph, I have a suggestion. Why don't you design a hybrid integrated amp at the level of Ypsilon or beyond with a great phono stage? And not $25k one.

^^ I have exactly that in mind :)

Great. 

Cannot wait.
