Kumisa 3 is fully discrete (there might be a servo there though) while Kumisa 2 was not.

Sijosae of Korea built a very different version of the Gilmore Dynamic amp. I happen to like it quite a bit. Take a look....

You can build one of these using Mill-Max Series 7600 In Line Sockets from Digikey.com! These can be ordered with the exact number of pins you need.

Sijosae's amps are beautiful to look at. Not being an engineer, I sometimes wonder if there is a price paid for his miniaturization--ie, is the shortest path necessarily the cleanest path? Never the less, his collection is quite cool.

ppl - "I at first used Kevin's power supply but later changed to My Dual tracking Discreet component supply using LED's as Voltage references to obtain no Thermal Drift"

ppl - "I did not like the sound of kevins Power supply made the sonys somewhat fat in the bass and this is not a good thing with these cans. Kevins Supply was OK in the Mids and High's presenting a fast quality but the Bass turned me Off so a Good regulated supply with Big Caps work nice."

I am very interested in learning more about fat-free bass and details of your PS. What is its current rating? Please post the schematic.

Kelly:

In a hand-built amp, short paths are fine! Inside an opamp or a buffer, they are even shorter. So I do not see Sijosae's miniaturization as a being a negative characteristic. Short paths are usually the main goal of an amp designer.

Hey, I enjoy your excellent reviews. So I hope you keep doing them in the future. Great work!
