I was thinking about unloading a crate of old tubes that I acquired through an in-law several years ago and was doing a bit of ebay research ... when I did a search simply by "tubes" and sorting by price ... this came up.  I'm surprised the guy hasn't sold a boat load of them to the audiophool audiophile community.
 

Yikes!  I think I'd rather spend that kind of money on a new car.  

Some people have million dollar ideas; then there's that guy.

Does he have more than one?  You probably should have a backup just in case...

I'm sure it makes the mp3's on that ipod sound like you are listening through a $50,000 system.
 
I love the guy's response to a question about having it installed in a box ...
 
"The box restricts the frequency respone due to stray capacitance."

It just goes to show that you should always have your capacitance neutered.

Maybe you should get two for stereo.

Good point.  So, you need four then?

Why not?  They're cheap.  

You can always hook them up to one of those Beatz headphones.
