I'm very pleased with my new HE400, great listening experience.
Thought about building a budget tube amp (<200$).
I need your help choosing the right one. A kit is better than schematics for me.
From the basic knowledge I've got on headphones I know that the HE400 have a low impedance of 35ohm which means I need a low voltage/high current amp.
* I've seen chineese kits on ebay. Any good?
** Maybe I should buy something like the AUNE T1 instead?
