Audiodharma Cable Cooker anyone share experiences?


I am interested in the Audiodharma Cable Cooker and would like to here comments from anyone that has actually used one.
Thanks,

Sean......the Cable Cooker delivers a steady state, multiplex signal measuring just a hair under 2 amps of current (for the speaker cable and power cable circuit), in addition to a swept square wave. I know you've expressed your skepticism before, but end-users, including dealers and cable manufacturers, can testify to its efficacy.

Power cables may also be daisy-chained without any practical limit and without any signal degradation. A major audiophile cable manufacturer, for instance, conditions 12 or 13 power cables at a time, in addition to their interconnects and speaker cables.

I hope this information satisfies your question.

Sean:

"As far as the power cords go, are you saying that they are fed the same signal as what is fed to the speaker cables?"

Yes. There are two separate circuits (and two separate signals)....one for interconnects (lower level), and the other for speaker cabling and power cabling (higher level).

"Out of curiosity, have you ever had any feedback as to how the CC stacks up against the Nordost unit?"

Another dealer, other than Joe Cutrifelli at JC Audio, has compared both. He sold his Nordost. Another customer did the same. This is third party, but they told me that the Cooker was "qualitatively better", and faster. Joe would have to comment further as to his experience.

"I don't know much about that piece other than it supposedly works on a timed circuit and is designed for "complete treatment" within 24 hours, etc..."

The CBID (signal) was primarily designed for their cabling and their dealer network, but I've never heard Nordost make this claim. And I sat in on a presentation at CES a couple of years ago. I think the 24-hour cycle is a safety feature, as Joe says, but one must repeat the cycle to get the cables more fully conditioned.

"Personally, i don't see ANY cable being fully burned in that amount of time but i know for a fact that the results are audible if you stop at that point using a Mobie."

Excepting for cables that have seen a good amount of time in a system, 24 hours isn't enough for a brand new cable. But on cabling that's been in a system for a while, 24 hours (on the Cooker) seems to be "enough". Customers are using their Cooker's for a recommended "recharge" every 3 or 4 months, finding that this overnight-to-24 hour conditioning maintains a high performance level for their system. As you likely know, break-in is a long-term phenomenon, but not a permanent one.

"How long do you recommend burning various cables for on your CC?"

Cooking time is dependent upon the gauge of the conductors, the number of conductors, and the amount of dielectric material. Generally, for brand new cable, the guidelines are 1 1/2 to 2 1/2 days for interconnects....2 to 3 1/2 days for speaker cables....and 3 to 4 days for most power cables (some extremely heavy-gauge designs could take longer). Of course, periodic listening tests are important to determine the optimal conditioning time for different designs, after doing what I call incremental periods of Cooking. There are some exceptions to the above guidelines, such as for the very light-gauge solid-cores and foils. One customer owns Mapleshade Double Helix, and found that only 4 to 6 hours did the trick, after trying to fully condition the cable in his system for a month.

Without intending to be promotional, you can find out more particulars by reading the Cooker FAQ's on my site. I'd be happy to answer any other questions or comments you have.

"Alan, i'll have to stop by your website and take a look at the info there."

Be sure to check out the Cooker FAQ's.

"Out of curiousity, would you be open to further comments, questions and possible suggestions via private email about the product?"

Sure.

"PS.. If you have it drop shipped here, i'll save you the trouble of breaking in the break in device : )"

Nyuk, nyuk, nyuk. Oddly enough, the irony is that the Cooker *doesn't* require any break-in itself....it's good to go out of the box. Keep in mind it's not producing a listenable audio signal that needs conditioning for better sonics.

Bob......some corrections to your statement.

I don't know where Mr. Brisson obtained his information, but the Cable Cooker does NOT put out *any* DC component in its multiplex signal. Period. The Cooker puts out a high-voltage, high-current, steady-state signal in addition to a swept square wave covering the audio band.

It may be that the capacitors in the MIT boxes are shorting the Cable Cooker at higher frequencies, causing the Cooker's power supply to immediately shut off. This is a built-in safety feature of the power supply. If it sees something it doesn't like (like a current or voltage aberration), it shuts off. Also, there would be NO damage whatsoever to the cabling.

Two Cooker customers had this occur to their MIT cabling. The LED's on the Cooker "blinked", as the unit simply didn't operate. They reinstalled the cabling into their systems and everything worked just fine. Unfortunately, no further conditioning could take place. Owners of Transparent cabling have no problem with the Cooker, nor does the Cooker have any problem conditioning Transparent Audio cabling. The LCR networks seem to benefit from Cooking, as do the cables.

Thanks for the clarification, Bob. I recently had a chance to analyze the DuoTech with the Cooker's circuit designer. I've been wanting to do this for a couple of years. We found a very strange multi-square wave being produced, that looked like sharp "hash" on the scope. While we didn't put a great deal of time into it, the signal appeared to have three distinct square waves but couldn't nail them down individually without dismantling the unit. The voltage also seemed to sag when a speaker load was placed on it. Speaker cable break-in is accomplished via 2 small rectangular modules that plug into RCA's on either side of the main unit. It seems that the same circuit conditions both interconnects and speaker cabling.

There was little current to speak of, as the the DC wall wart powering the unit was only rated 500 mA. That's about it, other than a comment that the signal didn't appear to be very efficient or powerful.
