Well... a video of me building an amp would have a bit less in terms of production values! But likely more entertaining in a comedic sense!! 
Nicely done! Thanks for sharing!!

Hi Geary.
When I posted that video,
I was thinking about my Bottlehead Crack headphone amplifier
that you have put together for me.

When I get my Crack, (Sometime in April)
I will bring it to the store that sold me my Sennheiser HD-650
and try the Crack amplifier with the HD-800 and see if the difference between the two
is as BIG as people say it is.
I am sure it is, but I want to heard by myself.
