The valves have been subjected to subzero temperatures for several days and then slowly elevated to room temp by a microprocessor controlled system. The treatment has been carried out by the worlds leading Cryogenic specialist lab. Tubes subjected to Cryo treatment undergo a molecular structural change within all the inner metal components which is known to relieve internal stresses and produce a more tactile, smooth and more rugged material. Great tubes made even better with the Cryo treatment. WHAT ABOUT THE TONE? These valves produce a very detailed tone with clear and emphasised highs yet somehow they seem able to produce that wonderful valvey fat tone. Even better tone than the normal tubes following the Cryo treatment.

Shaggy Posted April 2, 2010 Share Posted April 2, 2010 The cryo valves really are excellent - I've got a couple in my Eden VT-40 (thanks to Molan) and it runs totally quiet with a noticably more hi-fi response compared to my other valve gear. If I didn't already have 3 pre's I'd snap this up, but bump for a nice bir of kit Link to comment Share on other sites More sharing options...
