cyrogenic outfit recommendations

I'd like to get some recommendations on cryogenic treatment places, particularly ones that have a small minimum order or only charge by the part (because I won't have many parts to treat at first).

My Woo headphone amp uses an old TV tube type, the 6DR7. It can also use the 6FD7. Right now I can't find the perfect brand or type of tube. The "fat bottle" 6FD7's have gorgeous highs, but the RCA 6DR7 have much better bass, tonality, dynamics, while unfortunately having slightly harsh highs.

It occurs to me that cryogenically treating the 6DR7 might improve the highs (and other aspects).

Anyway, I'm sorry to ask this question again--I asked it long ago but somehow lost where I wrote down the replies. So my basic question is "pay by the part" cryogenic outfits. Because I want to start with just a few tubes and maybe an interconnect cable.

I also asked a couple years ago about the general wisdom of treating tubes and whether it puts them at risk. The consensus was that it's rare for a tube to fail, and most people feel it improves the sound.

It will be interesting to see if it smooths out the highs.

There are certain things that can make a big difference that many don't see how. - Michael Samra 19:33:24 05/31/13 (0)
