High end headphone amp

I just bought a custom made headphone amp off eBay and had to recommend it as probably one of the best sounding amps I've ever used.
I works off two 9 volt batteries so there's no a/c hum and it's nice and loud with separate volumes for each channel.
I'm using it with Akai K20 headphones and can't believe how clear they sound.
Like... no distortion... excellent seperation....

If anybody's looking for a decent headphone amp I'd highly recommend one of these.
I don't know whether he makes them himself but they're really well made.
