Hi Mike et al, What are your thoughts on the cryo treatment of valves? - beneficial, improved SQ, longer life or what? Specifically, having armed myself with a matched pair of 6922s for my MF X-100 clone and a single 6922 with matched triodes for my HA10 amp, both of which are a distinct improvement on the stock items they replaced, I wondered whether cryo treating them was likely to improve them further or maybe 'bugger up' the matching aspects? I would appreciate any advice. TIA, Dave.

Personally (as something of a dirty objectivist scumbag) I'm very wary of anything with the word 'cryo' in it. Cryo-treated valves, interconnects, amps, DACs etc... From my perspective going either side of the ideal operating temperature of a piece of equipment to extremes can't be a good thing. With things like metal expansion and contraction and if there happens to be any stray moisture on your equipment I can only imagine it damaging components or, at best, making no difference. Yes some materials might become superconductors near absolute zero, but as soon as you come back to room temperature the difference is gone.
Of course, to others it could be a total revelation that improves bass, gives higher highs and more liquid mids. I've never tried it myself so am only speaking from what I know about material properties.
