So my kiddo grabs a popsicle from the freezer, runs outside and sees his friends started playing soccer again. He sets the treat down and joins the fray. 20 minutes later Paco returns to a melted mess. He starts sobbing then askes, " hey daddy, is this why you keep your audio interconnects in the freezer?" I replied, "Yes son, it's also why I keep the basement at absolute zero."
The Future of Hifi is just being Discovered
I found this to be very interesting to learn that electrons move like water. Also even more interesting to learn Cryo really is on the cutting edge and it's implications for the future are just being learned. Fascinating stuff

Last time I bought tubes from Upscale Audio the salesman asked what "level" of tube did I prefer: 1. Good Matched 2. Excellent Matched 3. Kevin’s stash or 4. the best ones that are then cryogenically treated? What’s the cost is my question and the cryo tubes were close to double the price. I went for door #3. Interestingly, I asked him if the cryo tubes sounded much different, he replied that no they sound the same "But some audio guys just have to have all kinds of stuff cryo’d so we offer it as a service." I just shock my head. Regards, barts |
barts, Never get vacuum tubes cryogenically treated, its a scam and not healthy for the tube life. People do not understand that a tube has multiple parts of different materials that expand and contract at different rates. This causes stresses in the tube when you try to freeze it at cryo levels. One of the biggest failure points is the tube pins where they pass through the glass envelope. Another is the plates where they join to other types of metals. It is not safe to cryo vacuum tubes ever and your just adding to failure points if you do.

Something different, I suspect that electronic engineers don’t get any courses in Materials Science, Engineering Science and Strength of Materials as do some others in the field. All materials would benefit from cryo treatment if done right. I would not care for NOS cryo treated tubes but i would for cables, plugs, fuses and so on. Just saying. |
