GR Research B24 AC Cord Review

I won't buy his cables until he exorcises the demons from them.

He’s come a long way since the ‘dirty t-shirt’ .

Maybe he cryowashed it?

 

[Steve Dallas]

Pffft! It is obviously cry-dyed. That aligns and preserves the crystal lattice of the fibers. Duh!

Hold on to your hats folks! Danny has now cranked up his cryo freezer chamber:

View attachment 319756

The result, according to Danny, is of course much better cables.

Plus he demagnetizes them. Watch from 2:00 into the video:

Oh lord. When you thought it couldn’t get any worse.…

 

[DanielT]

Oh lord. When you thought it couldn’t get any worse.…

I know, it's totally crazy.

But okay, at least it generates fun comments about it here on ASR.

I really don’t know what he’s thinking crying treatment is so 2019… 2023 will the the year of high temperature annealing! It yields a much more stable crystalline structure and gives much smoother sound. And don’t forget the blackest backgrounds you’ll ever not heat!

 

[Speedskater]

'cryo' treating cords and cables can be very hard on the insulation. Also will void any 'UL' listing due to storage temperature limits.
While there may be minute gains to the copper conductors, it will disappear when the cord is flexed.

If you place the power wires on your ears, you'll easily hear the difference his power cords make.

Do the crystals give the cable the strength needed to do some heavy veil-lifting?

Although cryo-treatment for cables doesn't do anything for audio, there ARE some instances where cryo-treatment provides some benefit. I would think that automotive items like some engine or suspension parts might exhibit increased strength, toughness or resilience after such treatment. Maybe something like the shaft of a golf club could benefit- maybe even metal eyeglass frames - bicycle frames or wheels- fine quality knives - certain mechanical items like these could benefit. Maybe.

But not HiFi cables or other parts of the system, except MAYBE phono pickup cantilever tubes. Again a big maybe.

Now, that is not to say that cryo-treatment is completely useless in audio. I understand that placing audiophiles who are "believers" when it comes to wire in a bath of liquid nitrogen that the background noise in any listening room where they are present decreases markedly....

Yes. It is used to treat metals to remove slight imperfections in the surface to obtain better wear characteristics as told to me by a metallurgist. Probably, this is where the audiophile myth originates. Like all of them, a seed of truth is planted and cultivated via the waters of ignorance into a tree of stupidity

If you hang your reputation on cables you want to make sure their tensile strength is high enough. Depending on how big your reputation is, of course.

If, a big IF, now phono pickup cantilever tubes would be affected by cryo freezing, how do you know that pickup X is affected in the same way as pickup Y when they are frozen and then thawed? Sometimes for the better, sometimes for the worse when cryo is done, or? Would pickup X be better, or worse, if it underwent multiple cryo freezes?
Note given the thought experiment that this stuff would change during a cryo freeze.

If we talk about utilizing what the cold creates for conditions, there are some areas in electronics where this exists:

In electronics, cryoelectronics or cryolectronics is the study of superconductivity under cryogenic conditions and its applications.[1] It is also described as the operation of power electronic devices at cryogenic temperatures.[2] Practical applications of this field is quite broad, although it is particularly useful in areas where cryogenic environment exists such as superconducting technologies and spacecraft design.[2] It also became a special branch of cryophysics and cryotechnics and plays a role in operations that require high resolution and precision measurements.[3]

Cryoelectronic devices include the SQUIDs or the superconducting quantum interference devices, which represent magnetic sensors of highest sensitivity.[4] They serve as the backbone of applications that range from materials evaluation, geological and environmental prospecting, and medical diagnostics, among others.[4]

Yes, after a very short transient peak.

If copper can't be permanently magnetized, why would anyone care about copper being magnetized? There is some serious woo fu going on here. Demagnetizing copper. Kind of like non-alcoholic liquor. Once it is done, you just have flavored sugar water left.

Isn’t that what you start with when maken liquor ? Well at least then you apparently can reverse the process

Pruno! Made in plastic bags hidden by prisoners in their cells. Anything fermentable goes, and yeast is what is in the air and its spores land in the open bag. As for liquor, the process can't go backwards because it gets consumed. Pruno did have some sharp corners on it when going down, however.
