hospital grade or commercial grade receptacles ?

Hdm - I have not measured any cryo'd cable. For one thing, I'm not sure how I would measure the difference, unless the improvement was on the order of 50%!!

A run-of-the-mill 14AWG Cu cable has resistance of .0026 ohms per foot. So, a ten foot power cable would have about .03 ohms of resistance. The resolution of my test equipment is about .001 ohms, so the improvement from cryogenics would have to be big for me to see it. I don't use 14AWG cords, I use 12AWG cords, which are about .0017 ohms per foot, so, if I may ask, how are *you* measuring the difference? On what? In my opinion, a .001 ohm difference in a power cord is worth essentially nothing. Every outlet and plug I have measured, only to test for proper function, measure zero ohms (in other words, beyond my multimeter resolution).

Cryo treatments *do* change metallic structures. It's popular for good reason with brake rotors, for example. But it doesn't materially improve cables.

Eldartford,

Albertporter...The notion that a degree in physics inhibits thought takes the cake.

I am simply applying Irvrobinsons version of the truth and arriving at a logical conclusion.

His degree is obviously an impediment. He refers to it, clings to it and tells us we need a BS in it, then describes measurements with volt-ohm meters as though they were the last word on this topic.

Worse, he believes we should stand in awe of his degree and accept his words of wisdom in spite of our own experiences and what has been proven in real world tests.

I suggest he contact Jeff Rowland, Richard Vandersteen, Tube Research, Kharma, McCormack audio and others that are misguided into believing that cable (including power cords) make a difference.

I'll bet they are waiting by their phones to be "saved." Perhaps you could help him by dialing the phone for him?

Irv: For a science guy, you seem to be getting caught in your own lies. A few posts above, you say it can be measured with a $50 multimeter, now you're saying I need some pretty heavy duty gear! You crack me up!

Not being a science guy, I could care less. But I can tell you, BASED ON EXPERIENCE, that the cables and outlets I had cryoed measured quite a bit differently following cryo. It was not my multimeter (who knows, it may not have even been a multimeter), but belonged to the cryo vendor where I have my stuff done. And yes, it appeared to be a very inexpensive device! If you want to really educate yourself (somehow I doubt it), you can do a web search for Bayson Heat Treating and contact Mark there. I'm sure he'd be happy to give you the measurements. As for me, I could care less about the measurements; I'm only interested in the sound.

FWIW, I use a $40 DVD player as my digital front end, DIY power cords that cost me about $100 each and an $80 interconnect. So, I'm coming at it from a slightly different angle than Albert, but ending up with the same conclusion.

Don't belittle something you have absolutely no experience with. It just makes you look foolish.

Tbg, I like your writing style. Your argument is a little screwed up, but great style! :)
