My garage currently would cryogenically treat any components.
Jedinite, yes, that looks pretty nifty.
As I am in the midst of disassembling and reviewing several systems as seen in my WAF system link, I am reminded of how difficult it can be to crawl on the floor, behind racks etc with a flashlight to see connectors, not to mention clean or maintain components.
So again, the idea is that - in addition to a thoughtful, dedicated space for listening - a house (or garage) might also include thoughtful, dedicated space for storage, maintaining, repairing and testing components, cables, accessories, spares, media etc without cluttering up the main room.
After years of steadfast support, I am finally get a bit of a hard time for all of the wires associated with this hobby. (Actually, not from my wife, but from my mother in law!)
On reflection, custom lengths for all cables would solve much of the messy cable problem, so perhaps the dream workshop/garage would also include cable termination equipment.
