Cryo cable tour...

dBe · « **on:** 22 Dec 2012, 08:12 pm »

OK, here is the deal. I will be building 3 pairs on generic RCA interconnects from Dayton Audio MSC microphone cable. It is a very good value and makes great budget interconnects: http://www.parts-express.com/pe/showdetl.cfm?partnumber=100-225

RCA connectors are Furutech FP-126(G): http://www.furutech.com/a2008/product2.asp?prodNo=86

I will build them in the standard manner used interconnects with 2-conductor + shield cable. The shield will only be connected at the target end (source > destination) and the direction will be determined by the printing on the cable. Signal flow will be as we read: left to right. One or two will be cryoed. That is part of the test. Figure out which is which.

This is also a test of the ability to perceive, not just hear, as well as a questioning of paradigms. Is there a difference? Is it better? Do I care? Kind of a 'self confrontation' course in audio.

This tour will begin after the New Year. I have to order in some of the cable. What I have on hand is already cryoed (of course).

All you have to do to play is to pay the cost of shipping these to the next player. I will kick it off by shipping them to Control (John) and he will in turn ship them to the next guy and so on. Relate your results to Control via PM and he and I shall determine as to when we have a large enough sample to divulge the results. From that point on the cables can circulate forever to demonstrate the effects of my proprietary cryogenic treatment on conductors. It isn't just putting the wire in the tank.

Time to jump in.

I'm game. Your little requirement is understandable and very reasonable. It's a small price to pay for an experiment like this. I have one system built around an integrated (Marantz PM-11S1) in which that would be the only pair of interconnects in use. I'm quite curious, even if a bit dubious.

You might think about cryoing as an assembly instead of doing the wire and the connector separately.

This should be interesting - looking forward to all of these experiments/tests which should cause some spirited comments and could change outlooks.

IN, please!

Nice. I like the idea. I am in.

Kindly include me... I'll invite over some NY Metro area audiophiles to evaluate as well...

Sounds like fun, Dave! Thanks!

That is how I do things. Of course I cryo completed assemblies. It goes way beyond that though. It is your basic, multi-step process. OK, may be not so basic.

Edit: Cryogenic treatment can be easy - get it cold: -320F-ish. That is the transition temperature of LN2, more or less. Liquid He4 would be better at
-452ish, but it has gotten stupid expensive. Thank the guv'mint for that.

Cryo can also be more complex. How long do you keep it cold? Do you cycle it up and down? Do you cryo virgin materials? Do you cryo pre-stressed materials? Do you cryo parts while under stress? Do you cryo everything after assembly? Do you do all of the above? Or, do you do think any of this matters?

We'll see/hear, won't we?

Cryo me a river (frozen that is) to my door stop and I'll try them out
if you don't mind.

I suppose it could have been worse, "Don't cryo for me Argentina..."

You might want to try heating as well, that's what Siltech does as part of their "S.A.T.T." process. Or, blast it with ultra high-voltage ala Synergistic.

I'm in only because we need an accurate uncolored resolving system to use.

Like I said: I use a multi-step process. It isn't just dunking the cable(s) or wire. Heh, heh.

Well, this is coming along nicely.

It should be fun and we'll see where this all goes.
