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.

Eldart, if you can't hear cryo treatment effects you should not even consider using a system demagnetizing CD like the Sheffield/XLO I own. Its effects are subtle but in a revealling system like mine they are very welcome...
I remember once back at Brown in the 70s a friend of mine and I tricked a third friend into thinking he'd dropped acid with us. For an entire day he simply tripped alongside. We didn't own up to it until much later; he could NOT be convinced that he just swallowed an inert ink-spot! Cruel times....
Remember who's speakers are hanging so they are never properly time aligned. All net gains previous to the speakers would be masked by hysteresis distortion..Tom
It's over.

I have tried the Cryo'd outlet with every kind of audio equipment that I have (no tubes) and am unable to hear, or measure, any difference between the Cryo's outlet and the plain one. The best test (IMHO) was driving two identical monoblock amplifiers with the same (mono) signal, and listening to the output bridged across the two amps. Ideally there should be no differential signal, but gain and frequency response cannot be perfectly matched, so there is always some faint differential output. The sonic quality of this differential output, (many dB down from the amplifier output) is identical when one of the amps is powered first by Cryo'd and then by non-Cryo'd outlets.

I consider my experiment a success, not because it confirms what science would predict, but because I can no longer be accused of not using my ears. I gave it a good shot.

I have packed up the outlets to be mailed back to HDM. My thanks to him for the oportunity to evaluate this tweek.
