I saw on Headwize that Kevin Gilmore has a new amp topology out and I was wondering if someone tried it or want to build one ?!

Here it is (schematic):

Do you have any pics of a completed unit ?! Does it drive Joe Grado's cans better than the Dynalo ?!

I would guess that Dr. Gilmore is busy with alot of things. This is basically a FET output version of a Dynahi, so yeah, it should drive Grados better than a Dynalo, as it will output considerably more current. I don't know if anyone, including Kevin, has built one yet.

Maybe Kevin can shed some light on this... I really want to see where it's going.

It seems like he can't source any decent current production fets to build his circuit around.
