The cryogenic system consists of a large stainless steel chamber resembling an oversized freezer. Nitrogen is fed into it, which is stored in liquid form in a 3,000-liter tank outside the building. With the slightest heating, one litre of liquid becomes 600 litres of gas. This gas flows around the objects in the chamber and cools them. The process is controlled so that the objects do not come into contact with liquid nitrogen and the temperature is reduced very slowly - or more precisely by one to three Kelvin per minute - by the gas, depending on the contents within the chamber. This goes down to -180 degrees Celsius. This temperature is maintained for a certain time, then the gas in the chest is heated and then cooled down again to -180 degrees. Wolfgang Lausecker does not reveal what happens next. At the end of the process, which takes about 15 hours, the contents of the chamber are heated to 35 degrees Celsius so that no condensation forms inside the chamber when opened. Incidentally, the nitrogen from the chamber is simply discharged into the open air, since the air surrounding us consists of almost 80 percent nitrogen.

People do not get into this chamber. For cold therapy, Wolfgang Lausecker has a so-called "CryoSauna" with temperatures between -100 and -150 degrees Celsius. In addition to joint diseases, chronic pain, especially long-covid symptoms are successfully treated. For this purpose, a stay of two minutes, in this special type of sauna, twice a day on five consecutive days should be enough.

But back to our actual topic: I travelled to Stanzach with NF cables from Audioquest and Göbel High End. I will describe how the treatment at CoolTech affected the sound in the second part of this article. Also included were three LPs each from two different albums. I had taken them together with the comparison copy from one and the same carton, so they should have been pressed in direct sequence and therefore show no differences in sound due to wear of the pressing tool, for example. Years ago, I had already had some records cryogenically treated in Grenoble. However, the simple process - cooling, maintaining temperature, and returning to ambient temperature - had produced such minimal improvements that my spouse and I were not sure we would recognize the treated discs in a blind test. In addition, there was a rather high price, which prevented our sommelier du son albums to be sold reasonably affordable as "Frozen Edition".
