Cryogenic experience wanted. Constructive please

Had an entire Olympia LX preamp with its CPS power supply cryogenically treated Olympia LX There was maybe a very small increase in transparency in the sound produced by the preamp after the procedure.

As far as treating cables is not money well spent in my opinion as soon as you start moving the cables i.e.. bending etc. the effects of the treatment on the metal starts disappearing.

Only way for you to find out is to try it and then see what you find. As far as your drivers I'd be concerned about damage of the surrounds from the cool down - ask whom ever does the procedure for you they should have experience in what materials don't freeze down well.

Good Listening

My experience is pretty much the opposite of Peter's above for what it's worth.

I've cryoed entire components, but mostly very cheap units as "experiments". Results were mixed: one DVD player seemed to benefit much more from treatment than another, but both were very cheap players and are no longer around.

There's also much more potential for damage with thermal shock with entire components due to the much larger numbers of dissimilar materials.

I would highly recommend treatment of all cables (power, IC and speaker) and receptacles with one caveat. If you are going to treat all cabling at once, I would strongly suggest you seek out some kind of cable cooking device like the Audiodharma or Nordost and have everything burned in post cryo.

If you don't be prepared for a fairly lengthy and nasty burn-in process that may take as much as 30-45 days and with all cabling done at once and reinserted into a system, the cumulative effects of cryo without burn-in will be quite nasty.

Receptacles may be burned in on something like the Audiodharma; alternatively, two or three weeks on a household appliance with a strong current draw, particularly with a compressor that kicks in like a refrigerator or chest freezer, using both halves of the receptacle, should get you most of the way there.

In my experience, movement or bending of the cables has not diminished the effects of cryo (I've had every receptacle that my system draws from, including those in my line conditioner, as well as every cable in the system treated and most have been in use since treatment for 7-10 years plus), nor should it. All scientific evidence points to a molecular change that is permanent.

The cryo process strengthens materials, especially metals, and in the case of cables and internal wiring makes them better conductors. Cryo improves the performance of transistors, electron tubes, metal connectors, etc. The only caveat with cryo is that it is prudent to wait a week or so after receiving items back from cryo before critical listening as they can tend to sound a little strange until the thermal shock effects wear off. The cryo process is irreversible. Thank goodness for that.

Don't cryo a laser or electrolytic caps or speaker drivers. You could cryo the magnet assembly of a tweeter whose dome and faceplate can be removed. Tom
