I am pretty booked up right now and I would not want to ship outside the continental US but in the spring I could set up a tube challenge. Five tubes, concealed in PVC. One bottom getter Chatham if that is a favorite tube for some of you guys, and the other four tubes of my choosing. HeadFi probably frowns on any sort of money wagering but no one ever said anything about Bill and I betting a steak dinner and bottle of wine but that was eight tubes.
With five tubes you have a 20% chance of guessing that particular tube so I would want odds. Anyone who guesses right could get say a bottle of bourbon or scotch with a top price of $50 sent by PayPal. If you do not choose the correct tube you love and can hear such differences in, I would get the cash equivalent of a bottle of Camus XO cognac, or The Balvenie 21 year old port cask scotch. I would let
@bcowen know the tubes inside each casing before I send out the tubes so there is no doubt it is on the up and up. I would be going through some personal expense and risk in doing this and I would only use 6as7s and 6080's or such as the other four tubes because I would want the gains to match.
Naturally I do not want people conferring about the tubes so once you listen, you send your answer to Bill and he holds all of them till those interested complete the testing. It is unfair to give instant feedback and the next person in line knows that number 3 is not the correct answer. I would pay shipping to the first person and whoever receives the tubes pays shipping to the next.
This should certainly be easy for anyone who loves that particular tube and knows when they listen the bottom getter sounds better, and Chatham beats say an RCA or Svetlana or whatever tubes I happen to use.
