Best Headphone Amp ...

?!?!
 
http://www.ebay.com/itm/Tube-600-Ohm-Headphone-Amplifier-for-Sennheiser-HD-580-650-AKG-K240-Beyer-DT-990-/331094423899?pt=US_Pro_Audio_Amplifiers&hash=item4d16c3f95b
 
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.

    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 ...

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

    She worked for RCA in the manufacturing facility in NJ from the 50’s till the 80’s and didn’t know the first thing about electronics.  I suspect she worked on the manufacturing line in some sort of QC capacity.  When we accessed the storage shed several years ago, I told my wife to look for tubes (my wife thought I was crazy … but people bring things home from work).  Sure enough, a fairly large box of tubes.
     
    As far as I could tell, the tubes came directly off of the production line, as many of them had technical data hand written on them (in grease pencil or something), and the collection ran the entire gamut in terms of production dates from the 50’s to the 80’s.  At the time, I borrowed a tube tester from a friend of mine and every tube I sampled tested as it was supposed to according to the literature (unfortunately, except for the few that I destroyed while learning how to use the tube tester).

    He's also selling the specs by themselves - for only $29.
     
    So, he thinks parts and labor is worth $70K?  Really?

    ... you are welcome  The funny thing is, the back story about how we came about access to the storage shed is far more interesting.

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


    Screw the Beatz, I am going to be doing all of my mixing though this amp and the Flips Audio headphones/speakers (just flip 'em and you have a set of near field monitors).

    Grew up in Wood-Ridge just north of there and was a north Jersey-ite until about 2000 ... when I became a central Jersey-ite.
