It's possible that sonic improvements via cryoing cables and wires are not the result of lowering electrical resistance of the wire. For example, sonic advantages to cryoing CDs and vinyl records are not a function of electrical resistance, at least in the conventional way of looking at it. Hard to say what the real mechanism is for anything cryoed as no way to get in there and measure things, or even to know what to measure. Even if resistance is (measured) a bit lower after cryoing doesn't necessarily mean that lower resistance is the reason the treatment is effective as other factors are undoubtedly involved (e.g., CDs and vinyl). Unfortunately these "other factors" are very undocumented for audio applications. Even the pro cryo labs, for the most part, don't offer any real explanation, altho they've been treating audio cables, CDs and components for almost ten years.
The Great Cryo'd Outlet Test
Some have wondered about the Cryo'd outlet test that this skeptic has agreed to do, thanks to the generous loan of an outlet by another member. The situation is that the outlet, and its non-cryo'd twin have been breaking in for several weeks and I think we can agree they are ready for evaluation. Performing the tests will involve littering the room with various amps and speakers with the associated wires strung around, so, and I am sure you understand, I need to wait for a free day when my dear wife is elsewhere occupied.
A report will be made.
