The Great Cryo'd Outlet Test

stehno, did you, as mentioned above, own the very same outlet (non-treated) and have everything the same in your system, or was the improvement due to upgrading the outlet in general (treated or not)?

Dmoffitt, both are Hubbell 20amp IEC connectors. The one from Jena Labs is cryo-treated.

-IMO

Just to clarify things Ed, my suggestion regarding playing things for a few days did not have anything to do with the cryoed outlet needing to "warm up", but had more to do with the fact that your system for this test has changed, even if it is minimal, and the subsequent change in sound due to that change (even without a change in outlet) may be something you have to adjust to. Under these circumstances, it might be adviseable to listen for longer periods of time(even if it's 10-15 minutes) to adjust to those changes, then perhaps listen to the same piece of music on the different outlet right after that. How about having your wife listen?

Good luck and keep us posted. Even if you hear no difference, I'm happy you've done this and don't feel that anybody should be "beat up" here. We all have to come to our own conclusions. You're to be commended for the experiment.

I think I stated in a previous post that I noticed barely audible improvement immediately after installing the one cryo-treated ICE. It was not until perhaps 48 hours later (24 hours of system uptime/burn-in) that I noticed the surprising improvements.

There were no other changes to my system at all within days of before, during, or after this install.

-IMO

I have a close friend who's a piezo-transducer wiz, making what are arguably the best pickups for acoustical instruments, and OE supplier to the guitar giants, too.
He told me there was a cryo-craze back a few years ago among the guitar string manufacturers...but it proved to be not real to ANYONE after awhile. And there's where you'd REALLY expect to hear a difference. He's also tried cryoing his ultrasensitive pickups somewhat, but has no positive expectation. His engineers and test people obviously have sensitive ears, always listening for not-yet-measurable artifacts that nevertheless sound "better" in transducing an acoustic vibration into an electrical one to his staff and the large group of pro musicians who endorse his products (Fishman Tansducers). Cryo is certainly NOT on the list of manufacturing tricks....
I'm willing to make up a couple of my PoBox9 with one each cryo and non-cryo duplexes, unmarked, to send around for trials. Hard-wired PC will be my PCK9. The problem, of course, is that we're only adding MORE hardware in the chain, and since performance WILL be determined partially by duplex and circuit line upstream, the additive hardware itself may slightly mask any diffs between the test objects (the dupes). In other words the dupes may get duped....
