Sennheiser HD800 - $800 (albany / el cerrito)

Barely ever used it over the years since purchase.
I don't even think it has seen even 10 hours of use, leave alone the long burn in of 400 hours that's recommended.
People who are looking at this listing know these are at the pinnacle of audiophile headphone equipment.
Been sitting in storage and figure it'd be better if someone got good use out of it.
I also built the bottlehead crack tube with the speedball upgrade amplifier for it that sounds amazing with the HD800.
I'd be willing to get rid of that for another 200.
The kit itself cost 400-500 dollars and then you have to assemble it.
I got better tubes that the ones that it came with.
The input tube is Amperex "Made in Holland" 12AU7A.
The power tube is a Tung-Sol 5998 So overall excellent deal.
You're welcome to come try them on.
