I actually made a CMOY amp that worked but when i plugged in my gumstick and ad700 on it....a high pitch sound came up and i did it twice. lol. hopefully my cans are still fine. I changed the IC chip and there was sound but the vocals just sank like the singer is singing miles away while the instruments are just right beside you.

Bought an amp kit, from ElecSumo on ebay. Its the banzai jelly kit.

But i broke the switch so yea...first attempt , horrible soldering. lol

But it works, serious volume for small thing like that. Increases some soundstage tooo on closed cans

Nice where did you get it from?
