Music Direct CryoAcoustic Tube Treatment
Tubes have long been renowned for providing unparalleled audio experiences. But did you know you'll hear even better sound and enjoy longer tube life with our cryogenically treated tubes? The improvement is so profound, Music Direct no longer offers any tubes that are not cryogenically treated. We have invested in our own cryogenic machine, allowing us to do our own in-house testing with temperatures and ramp up/ramp down cycles to maximize the effects on the materials. Countless hours of listening tests have confirmed the advantages of CryoAcoustic Treatment.
The cryogenic process involves cooling materials to very low temperatures through the use of liquid nitrogen. Temperatures reach as low as -190 °C, and the process registers a profound impact on the mechanical properties of materials – particularly metals. Used in aerospace technology, medical tooling, musical instrument construction, critical automotive components, high-pressure cutting tools, and performance-critical sporting goods, cryogenics considerably improve the sonic presentation of vacuum tubes, cables, transformers, and other audio-related products – as well as their internal components. Resistance to corrosion, firmer hardening, and added strength are just a few of the scientifically proven effects of cryogenics. And while the sonic benefits cannot currently be scientifically proven, listening tests confirm an increase in acoustic resolution – which is why we call our process CryoAcoustic Treatment.
