Audiophile equipment is nothing like a multistage cryogenic refrigerator. It's made of pumps, seals, heat exchangers... and when you're using helium 4 as a coolant you really need zero leakage because it's an extremely expensive. And yeah, microwave systems need amplifiers going up, and filters going down. But they need to be extremely efficient -- and also entirely non-magnetic. But unlike audio, these components need to be linear in the gigahertz, not kilohertz. There's some similarity, but huge differences. It's weird that the title focuses on cables. There's a ton of expensive, labor-intensive components that can be bottlenecks.
