Cryo Conditioning of Components

Outfitter03

Looking for experiences or feedback from individuals who have Cryo Treated components. Wondering if some forum members have Cryo Treated tubes, connectors, cables or inductors and specifically if they have noted a positive difference following the treatment.

I am fortunate to have a facility relatively close to where I live that allows customers to pay a bulk fee for Cryo Treatment starting at $7.50 a pound with a 10 pound minimum. Looking for some feedback and lessons learned, both good and bad before I try this out on some of my DIY supplies and possibly a few tubes. This is a dry treatment facility.

The first tests were listening tests. These tests were conducted as single-blind A/B comparisons with the Empirical Audio staff only using our reference system. The results from these were unanimous: that the treated cables sounded like listening through a cotton-filled tunnel compared to the untreated cables. Significant loss of image size and depth was noted. Also the dynamics seemed to be constrained or compressed.

Just 1 opinion of many I am sure.

Thanks Pepster. I have two comments on that study. The first is that they were testing on Silver Cables. I have also read on the VH Audio site that of the metals they have experimented with: Brass had the most significant improvements, copper was significantly better and silver and items with multi-metal plating sometimes improved, sometimes degraded.

The study listed also was a 12 hour direct immersion that temperature shocks the component both in cool-down and warm-up and would predictably produce micro cracks. This is a wet method, though in defense of wet methods, some have progressive controls to limit this temperature shock affect.

Thanks for the input as these are good points. I have seen tubes sold in the flea market here that are cryo treated. Any input from users on improvements.

I would not spend the extra money to have this done on a component. That being said, if what I'm looking for has been cryo'd and the price is right, I would buy them. A good deal is a good deal.

Perhaps I will hear a difference eventually but to date have not on the dozen or so items that I own with the cryo option.
