Hifimaniac, I absolutely agree. My first real experience with cryo-treated products was Jena Labs cryo-treated Hubbell 20 amp IEC connector to replac standard Hubbell 20 amp IEC connector on my amplifier's passive/dedicated line conditioner.
I had purchased the Jena Labs unit a few years ago and it sat around in my tool chest until about 4 months ago. Obviously, I was not anticipating anything or else I would have installed it a long time ago.
But after about 18 hours of play time, I was amazed at the sonic improvements of just that connector.
I've since installed cryo-treated plugs, connectors, outlets, etc. and I now have a box of 150 ft. of 12 gauge cryo-treated romex that is just waiting to be installed.
Cryo-treated items are a fantastic and cost-effective means to get at all the little musical nuances.
