If only I coould find a quality local cryoing outfit!
I would definitely do my Pangea power cords, and perhaps the long interconnects from pre to amp (7 meters)
If I liked the results..
Then i would be interested in doing my Bryston BP26 and it's powersupply, along with the 1.5 phono box.
If I liked that too, I would cryo the Bryston 4B-SST2 amp.
However, this is just a dream.

My question is: what is Bryston's position on cryo'ed gear. Is it covered under the warranty? Or, does the process make Bryston feel the items are 'modified' and not eligible for warranty?
Has anyone at Bryston done Cryoing to Bryston products? what is Brystons position on this process? No problem, it's good, it's bad, do not do it! or We have no idea...

Finally, has anyone who reads this had stuff cryo'ed and was it worth it?

I purchased cryo'd tubes for monoblock amps and the difference was unbelievable. Absolutely wonderful sonics coming from the amps. The amps easily sounded like they were much more expensive components. Based on that experience, I am a believer.

At my work we cryo treat all of our high speed steel (that would be M4 high speed steel) milling cutters after they are heat treated. What that does is finish the heat treating process and make the steel harder. What the hell it well do for cables? Now if you were able to get and keep your cables at around
-300F you might have some thing. I have asked some of these questions (about cables ) to some of the people at my wife's work and you should hear some of the things these physicists had to say ( after the raised eye brows and laughing), anyway
my wife works at Fermi Lab. I think I might belive these people a little more then that guy at the stereo store. But then again many people well hear what they want too hear. Save your money buy more tunes kick back and turn it up 
 That's my 2

I know the benefits of cryo treatment of audio cables and equipment as well as optical media (CD, DVD, SACD etc.) is highly controversial; however, friends I know swear that cryo treatment does help stengthen solder points/joints.  Hence, perhaps with all the solder points in electronic equipment, such cryo treatment could help to stengthen those solder point?  Not sure.

All I can say is the last time I was frozen my performance suffered.

I don't suggest doing that...there is sufficient PRAT going on in Bryston...you may CRY after the treatment.

Cryo treating cables can help reduces the cable’s resistance ..

When the raw Steel/Iron is made/drawn .. gases are trapped in the manufacturing process at the molecular level and create additional  spaces/gaps between the crystalline grain structures ... when the current/signal runs into theses gaps it has to jump the open gap and  meets with additional resistance to cross this space

Cryoing drives out most of these gases (and other impurities) left behind from the manufacturing process by squeezing the molecules closer together in the freezing process ...    and that reduces the boundary distance between the crystalline grains .. there by reducing the gap distance the signal has to transverse which reduces the wires resistance

Read any Cryo Treatment facilities' home page and you’ll see in their claim's ... that in addition to extending tool life... it reduces electrical resistance

OHAN OCC  Cast type wire is another attempt at eliminating these boundaries between the grains ... this is their attempt at reducing resistance

And if you want to reach back even further let's go back to B.C.   .. (Before Cable) ... silver has  longer grains than copper with less boundary gaps per meter which may account for it’s higher conductivity rating over copper because with fewer boundaries it has less resistance

Obviously the Physicists must have skipped class the day we discussed this

The spaces/gaps between crystalline grain structures have nothing to do with how well certain metals conduct electricity and it has nothing to do with lower resistance (higher conductivity) rating of silver over copper at room temperature.
There is lot of nonsense and sometimes utter BS in marketing attempts to push products.

Well said, it is well known in what applications and materials cryo treatment is beneficial, applying it to a product made of so many different materials that serve different purpose and react differently to temperature extremes (power cable, or even entire and complex devices), is nonsense. Doing it so to conductive parts of a connector of some sort, made of materials that indeed benefit from such treatment I can understand, but what is being peddled in audio is BS.

Interesting topic - but there's a better and easier method:

I always put my brand new cables at the bottom of a chocolate fountain. Then you have to heat up at least 2 lbs. of chocolate.
Meanwhile the fountain is running, the circulating chocolate causes all electrons from the valenz band to jump into the conducting band - that's because almost every electron likes chocolate and they are getting so excited.
Therefore you get more conductivity - the sound will be much "sweeter" than before.

I can't proof this effect with any physical law, but there really is a difference! You have to try it yourself.

Have you ever heard cryo treated cables ?

Yes I have, and your question is completely unrelated to what I said.

[Rclark]

I own cryo treated cables and there is absolutely no difference between them and my cheap Radio Shack wire. Not one bit.

I would not go that far, there can be audibly significant differences between various analog interconnects, digital cables as well as power cables, depending on what equipment it is used on.
This however is the result of completely different factors such as cable construction and materials used that influence parameters such as for example capacity and inductance, which in turn impacts operation of interconnected components (i.e. pre-amplifier may sound different when another interconnect is introduced between it and amplifier), and not something that woo-doo scientist like to promote.
Another point is that it may sound different but not better. For example there is nothing better in situations where a change, no matter of what kind, causes a few dB emphasis in presence region and makes one perceive this as an improvement in transparency or details.
Very few have a real reference in the sound of real instruments, voices that all are familiar with are not enough to subjectively assess performance of any component, so majority of opinions expressed in forums are just opinions and are far from something that can be taken as valid assessment. In this kind of environment it is easy to promote BS.

what cables have you used? just out of curiousity.

the valenz band

The Valenz band? Is it a three piece or four piece band? What kind of music do they play?

I would think that freezing wouldn't be good for some of the components inside active electronics, especially power supplies. Since most electrolytic capacitors are 'wet' there may be a chance of rupturing them or for crystals to form which might cause damage to the aluminum oxide, the electrodes.
