Last year, an audiophile read our posts on (a) Cooking 4-pin XLR cables, and (b) their use on Simaudio's 820S outboard power supply. An octogenarian, he asked that I refer to him as "Crusty Old Audiophile," or COA for short. He said that his son was, well, my age, which explains why he referred to both his son and me as "kiddos."

COA emailed, "I don't have no high falutin' [Simaudio] Evolution, like you," but he did have Simaudio's 310LP phonotstage, plus 320S outboard power supply. These two Simaudio "Moon" series products utilize a 4-pin XLR cable.




COA knew of a small handful of audiophiles who owned an audiodharma Cable Cooker. But none had adapters needed to treat 4-pin XLR cables. So COA reached out to me. "I was expecting you to be a kid," he wrote. "I didn't think you'd be so darned professional." So he shipped me his OEM Simaudio 4-pin XLR cable, which is identical to the one which came with my 820S. Don't forget; in this cable, the male XLR comes first.



"Unlike you and my son," COA emailed, "I ain't into digital." Maybe because COA doesn't plug and unplug his cables, his 4-pin XLR cable did not have as many scuffs and paint scratches as mine and my friends'. While his cable was away, he plugged the powercord directly into the 310LP. COA said that not using the 320S was a letdown, the sound becoming limp, confused, lazy, and undefined.



I left COA's 4-pin XLR cable on the Cooker for 4.5 days. Ridiculously, USPS took over 3 weeks, to have the small box containing the cable go from the Bay Area to Texas.

COA wrote that his "eyesight ain't what it used to be," so he had his son take off the 310LP's lid, and make the gain and loading adjustments. And that was where they found the Cooked 4-pin cable to exert itself. Before Cooking, making gain and loading adjustments was "a guessing game." But now, COA and his son could hear what each change was doing.

Making no changes, COA said that the Cooked 4-pin XLR cable makes the 310LP track a wider soundstage. And grain and noise he thought were part and parcel of the turntable (VPI Traveler) were actually the 310LP/320S.

COA re-read the reviews of the Simaudio 820S, especially when used on the 610LP phonostage. My friend feels that, with an 820S, his 610LP more strongly sniffs whatever his turntables, arms, carts, and cabling are doing. COA agrees that something similar is happening with his 310LP/320S.

These 4-pin XLR cables are for DC power. They do not carry actual audio signal. So we would think that Cooking them would not amount to much. But we'd be wrong.

Great looking cable- Lummy.

Having just recently re-engaged with the hobby and AA, and so I apologize in advance as I haven't read the previous parts/posts on the subject, how do/can you 'cook' a 120v power cord on that doohickey?

If possible to cook power cords, does it apply full wall voltage/current?

I read through some info on their website after my previous post, it appears that the power supply on the cooker is 12v. I guess that is sufficient in 'conditioning' a power cable.

Interesting, but those cookers are a bit on the pricey side. I'll just have to make do with listening to music.

 

Adapters to treat powercords, posted on January 26, 2021 at 16:58:13

If you take a look at the face of the audiodharma Cable Cooker, you will find binding posts, RCAs, BNCs, and 3-pin XLRs. To treat other cable types, you use adapters to convert to plug type, and back.

In the OP above, you can see that we sourced 2-RCA to 4-pin XLR adapters. In high-end audio, 4-pin XLR cables aren't common. They are primarily used in DC applications.



In 2003, this Cooker originally came with these adapters, which treat the + and - of powercords. Yes, there is also a 20A adapter.



Years later, this so-called Ground Breaker adapter came out. The GB treats all three legs of a powercord.

The 12V supply is only one portion of the special multiplex signal, which by the way is a steady-state signal....much more potent. The other components are high-current (in differing amounts....125mA for the interconnect circuit and 1.9A for the speaker cable/power cable circuit) PLUS a swept square wave that is calibrated from 0Hz to just over 40KHz in range. Add in the harmonic multiples, you have a frequency sweep reaching into the megahertz range.

The HI-POWER version uses a 15V power supply plus some custom power resistors, enabling the current delivery to increase to 150mA for interconnects and 2.5A for the speaker cable/power cable circuit.

Maybe send some cables to Lummy and find out what the fuss is about....

Thanks for the info Alan, and nice of you to offer Lummy's services. But am thinking there is an arrangement between the two of you that need not be explained.

I have been using the same cables in my system for a very long time, and would like to think that they are fully 'cooked'. I have had equipment upgrades over the years but have kept to the same cables, as I'm not that picky :).

I have audiophile acquaintances who either own, or have access to, devices from audiodharma, Hagerman, and Nordost. I myself have had this audiodharma Cable Cooker since 2003. It's been in pretty much constant use, over those 17 years. It has seen, if the cables were new and at retail price, well over 1.5 million dollars.

People send me quite a few audiophile cables from as far back as the late-80s. Thus, many of those "old" cables had been in use for decades. Such is the case, with this balanced AudioQuest Lapis. Its owner says that he bought it new in 1993-94. It's been used for most of the time since. Just an overnight stint on the Cable Cooker extends, or goes beyond, what over a quarter century of regular use does. But for full effect, the Lapis (this Cooker has treated over a dozen) has an optimal Cook time of 4 days.

Lummy is quite gracious and offers his Cable Cooker without cost, which I thought would be eminently fair to you, for a try-out. Just that simple.

Thanks for the info Alan, I wasn't implying anything with my previous post. I'll read up the info on your website.

Thanks in advance for the 'offer' Lummy, but am content at the moment from what I'm hearing on my system. Have a couple of upgrades planned, but in no hurry. But it's awesome that you are willing to help our members with this.
