Sakura Systems OTA Cable Kit

Just an update:
*Cryo'd OTA to use in my NEAR M50's Tweeters\Midrange
*Bass Drivers Un-Cryo'd
*Tested IC's using the cryo treatment

Seems there is more presence using the Cryo treatment with Copper WIre.I would not venture to use it with any Plated or Silver Cables.

Speakers sound great with the OTA.They are not fully broken in ,but I know it was well worth using it to do the internal wiring.

The comment of Presence!
I noticed it most using Classical Guitar Recordings.Tried to find the best word to describe the essect and Presence is it.

Also Used A run of Belden Digital.Cryo'd and Uncryo'd to do the test.

Have fun!

Abex, how did you arrange cryogenic treatment for your OTA cables? Where did you send them? What exactly did the treatment consists of (in exact times and temperatures)? How much did it cost?
Rewiring speaker cabinet interiors with OTA is well worth it. Also worthwhile is rewiring umbilicals between the RCA female plug and the circuit board (since sometimes these can be a substantial length, and use inappropriate wire).
Your comment on the sound of cryogenically treated OTA indicates enhanced conductivity around 5 kHz.
But isn't OTA already cryogenically frozen during the manufacturing process in the first place? I think that this was implied in an earlier post. In any case, that would explain the strange sticky feeling of the polyethylene covering everyone reports, since viscous particles travel to the surface during cryogenic freezing.

Slawney:

I had thought the OTA insulation to be Teflon (when soldering the OTA the insulation has a very high melting point, like that of Teflon).

I had the OTA cryo treated through Kimber. The only thing I know is that they did take the gauge into consideration when doing it. Ray Kimber I thought would know what he was doing.

If the OTA had been Cryo treated initially it would not have made a diff.. From what I have read from others having it go through a Cryo treatment a second time enhances the results. This has been written by those who have Cryo'd Outlets.

I had thought that the reason that OTA was different or had different sonic characteristics than other cables was because of the Die it is run through. I guess no one but Yoshi and the Wire Manf. that ran it would be able to tell you what is actually going on for cetain.

I know a Metallurgist that might be willing to work on a test using inexpensive cables in order to see what exactly is going on with Cryo and weather it is feasible to bring up the sonic quality. It should be intresting.

If there is enhanced conductivity that explains the effect. I know that there is longer lasting Decay of Cymbals and High freq. instruments. This was testing and impressions .Both my new speakers and the other speaker I had previously use the same Tweeters. Might it be the activity of the XO's also? There is more breakin to do ,but I am very impressed by what is happening thus far.Wish I had more cable to use with my SS speakers internal wiring.

Next I will change the values of the Caps along with the Manfs. of the Caps\Resistors in the Tweeter XO's to bring the performance up another notch.

Anything you can tell me would be appreciated or if I can add anything you want to know ask!

47Labs OTA Cable Kit:
It might not be for everyone, but it turned out to be a jewel of a deal for myself.

I was within days of buying the first of several cables for my system and I was lucky enough to had gone to A-Gon to see what was going on in used cable. Someone had just put up the OTA kit for around half the new price because they did not like what it did in their system and I immediately mailed him. He had taken it off right after or before he read my mail to increase the price, but he was so disenchanted with it he decided to just sell it to me.

Since buying the cable I have made all the IC's, made a run to my main speakers and had my newly designed speakers wired with it. All for a fraction of what it might have cost if I were to buy separate cables for my system. The only place I do not have it is between my Transport and DAC.

The thing that really made it worth it was the fact that Yoshi's new speakers (Konus Audio Essence) or the replica's of his speaker made from Carolina's(?) look like the NEAR speaker drivers that use to be used in my cabinets making synergy less of an issue.

Since getting my new speakers online wired with the OTA I have noticed some great traits of which I might not have had if not for wiring the internals with it. For one it has made decay of instraments better than I have ever had with any of the other speakers I have had in my listening room. I have had PSB's,Magnepans and other NEARs.The new drivers are true of the presentation of different instruments also.The nost apparent of these are Cymbals.Love the long decay and true to life emphasis which is given now.Another trait is the disappearing of the speakers. I have never had speakers that completely not show themselves making the music. At no time do I hear anything which tells me a sound is coming from a driver. The Maggies never did this and they were the most transparent speakers I ever owned up to now. Well then again the NEAR M15's I think betterd them,but it was kinda a coin toss.

Anyhow the OTA Cable has been a godsend for my purposes and I hope others might find suitable cables for their setup.

Note:The Tweeters have Cryo'd OTA running to them and the Amp-Pre IC is also Cryo's with Eichmann Plugs used.

I will still try out another Digital Cable soon with my Belden as a reference to beat.

Dekay: good to hear from you in so long. The identity of the OTA insulation can be a confusing issue. Sakura Systems listed it as "teflon" in an old information sheet for the "open technology" cable kit. But recently another 47 Labs distributor confirmed to me that it was polyethylene.
As you probably know, polyethylene is the most popular plastic in the world--used for grocery bags, shampoo bottles, children's toys, even bullet proof vests. As to what type of polyethylene OTA insulation is, I do not know whether it is branched-low-density (LDPE) or linear (HDPE) or some other variety. Nor do I know if OTA insulation is made by free radical vinyl polymerization, Zieger-Natta polymerization, or metallocene catalysis polymerization. From the physical features of the OTA jacket, my vote goes for branched-low density with some type of dye, which means that the OTA insulation jacket has some irregularities that will affect the sound, irregularities that are only partiallly overcome by break-in and cryogenization. I do not think that the blue-green dye is meant to enhance the performance of the cable, but that it is used to give the cable an attractive color.
The fact that I can get the OTA insulation to melt already at 280 degrees C shows that it is not teflon. Teflon has a melting point of 327 degrees C. Also, OTA insulation does not undergo "cold flow" like teflon.
Abex, I do not doubt that there can be benefits from a second cryogenic treatment. My question was directed more at the specifics of the actual procedure and how you arranged it, since it is unlikely that any of us can do this at home.
Upgrading speaker crossover components is a rewarding modification route: the chokes on the woofer and the capacitors on the tweeter are the most important to upgrade in a two-way crossover. Another good tweak is to leave the crossover outside of the cabinet on a stand of its own midway between the amp and the speaker cabinet. This reduces microphonics that will make a speaker sound more distorted and unnatural.
