cryogenically treating tubes - Page 2

If you don't have anything to contribute to my question, which is directed at people who have actually tried cyroed tubes, I think it would be polite to refrain from posting.

Even if the change from cyroing stuff is small, small changes can be important because of their cumulative effect.

I used to doubt that small changes were important or that anyone could reliably hear small changes. But, the guy who does my mods works by implementing a large number of small changes, and he uses his ear to detect/balance/optimize the changes. The result is fantastically good. He's convinced me that a series of small changes can get you to a large change in SQ that is easily audible. A lot of the things he gets from his designs, like expressive dynamics, I have never heard at this superb level before, not at the price level that I'm paying for the mods. Maybe stuff in the $10,000 range can match it, but I haven't heard that stuff. I just know that it's very cost effective if your target price for components is around the $2000 level.

For isntance, doing the headphone cable right seems to have a large effect. Stock, my LCD 2.2 were good but the imaging was flat. With the new cable, they have 3-D imaging with substance and depth and air. The new cable restores some of the upper-end extension which is the weakness of the Audeze.  It's a huge change that everyone at the LAX meet could hear immediately.

EDIT: re the dampers, yes I use high-temperature silicone rings, two per tube, which you can get for less than $1 each from Ebay or Michael Percy
