Review: CH Technologies X15 power cord Power cord

I am surprised you have added that contingency after hearing what the digital cord did in your system. I have made a lot of expensive audio purchases based on gut instinct. What does your gut tell you Gary? You have cycled through many PCs in the last few months. What are you looking for exactly?

Krellman, this sounds like a good product. I scanned the website, but there is scant data regarding the science behind them, proprietary elements, etc. What is the scoop? Copper, silver, magnets, proprietary winding scheme (who doesn't have that these days)? What is the designer's pedigree? Engineer? Scientist? Inspired enthusiast (aka DIY)?

Agear,
Greetings! Some of the questions you ask were addressed in the comments at the other review that was posted by Krellman.

In short, the proprietary element of our cables is the specific geometry. To claim anything else in a modern cable (Ie. materials) is "proprietary" is simply a canard. It doesn't matter who is claiming it. We use the best materials available. Period. But we don't spend time focused on that element simply because so much of the cable industry revolves around clever marketing BS and, in come cases, flat out lies. We are not marketing geniuses, we are scientists. So we stick with what we know.

Our pedigree is a conglomerate of engineers, physicists and various other scientists. A few men are responsible for the final design. But it would not have been possible without the knowledge base and various direct contributions from some of the greatest scientists in the world. Literally. We never mention who exactly for two reasons. First, because it distracts from the cables themselves. We believe our product to be unmatched, and so far this has proven true. But knowing who is behind all aspects of the design would be cumbersome and ultimately will not let your ears know what they can do for your system.
The second reason is more practical. It turns out that the end design has appealing applications in other scientific areas. And some of those who contributed to the project are doing further research in their own specific fields. They are doing this on their own and we are facilitating it by not mentioning who they are. The competition between Universities and laboratories can be fierce. We don't need a singular University preemptively claiming credit for future discoveries.

Regarding the "sparse" nature of our website. What you say is true. Again, for two reasons. First, and again, because we aren't marketing geniuses. What started off as a professional "science project", so to speak, turned into a product that was unmatched in performance. But it was the enthusiasm and word of mouth of a handful of audiophiles that literally dragged us into the market. We don't intend to ever be as big as a Nordost or an Audioquest. Frankly, that would never work with our product anyway. We're content with being an artisan shop that delivers the best products on earth while engaging directly with our customers.
And that's the other reason for the sparse nature of the website. It's designed to encourage those who are truly curious to engage by contacting us directly.

Even so, this summer we've been working on a number of short essays that reveal a deeper understanding of what we are all about. They don't get deep into specifics of the product, such as copper versus silver, because that's not what makes our cable unique. But it does provide a platform whereby we hope that music lovers can connect and maybe say to themselves, "Yeah! That's what I'm looking for too".
We have a couple more to finish before posting them. But hopefully within a week or two they will be up.

Thanks for your questions, Agear! We appreciate the interest. And please do, if you have more questions, contact us directly with the email at the website.

Cheers!

Correction:
We've gone ahead and posted the first five essays.
They are on the website and may be downloaded right away.
They are PDF files.

Thanks!! Happy reading and Joyful Listening!

I am curious. Now humor me. I come from a long line of scientists, have 20 years of education under my belt (medicine), including 4 years of research slanted towards the material science side of things, patented something during medical school, etc. I appreciate good science and innovation when it is there. Time and phase alignment seems important in audio. How did you measure time and phase accuracy in your cable?

Good question, Sir.
First, and for the most part, when it comes to measurements Time is directly linked to Phase. It's just more impressive to say Time AND Phase. But it's mostly just the actual time aspect that we are measuring.

Now, as to HOW we measure, that gets a little more complicated. And, to be honest, too great of an explanation could potentially reveal proprietary information. So let me handle it this way. To prove that there is efficacy in measuring the time domain in cables, let me point you towards an already published paper on the matter. Nordost has done the audio community a great service in publishing a PDF at their website titled "New Approaches To Audio Measurement". It's near the middle of their "downloads" page. It's a great paper. Everyone should read it.

What they demonstrate is a method to measure aggregate time distortions in audio equipment, including cables. What we've done is identify the individual aspects that lead to these aggregate time distortions and figured out ways to measure each individually. Basically, anything that stores energy has a time component associated with both the build-up and the release of that energy. Cables have more than one means of storing energy when exposed to alternating current. We've done our best to address each one individually. The end result is a significant reduction overall.
