Since a number of years between tests I "rinse" coaxial cables with clean filtered DC current between tests to get rid of interference signals left over from previous (failing) EUT. Make sure that the dirty left-over current resulting from this action is not contaminating your lab...

Back when Monster Cable was making their claims, I realized that these people are actually very smart, they have found a way to make a direct connection between your emotions and your wallet. At that time I conceived the idea of a company called Kabel Doktor. The premise was, "All cables deteriorate over time, it is an unavoidable fact of life. Annually you need to send your cables to the Kabel Doktor for proper cleaning and full spectral degaussing at the sub-atomic level so as to eliminate any surface charge carriers that may have built up as a result of cable skin effect. These stray carriers result in constricting audio energy flowing down the length of your cables by effectively reducing the cross-sectional conduction area. As part of our degaussing process, we provide charted analysis of the before & after spectral transfer characteristics of your cable, so you can now have the confidence you need for a full audio listening experience. Our basic service will test your cables from DC to 300 kHz, for an extra fee our top specialists, using high-end spectrum analyzers, will use our proprietary process to test on the other side of the DC frequency barrier. This will ensure that your negative curvature imaginary frequencies are also! part of your listening experience. Never be embarrassed again when you have friends over and want to play your latest full spectrum symphonic audio selections." Only, I just couldn't bring myself to do it.

It is interesting in how over time PT Barnum’s observation about a “sucker being born every minute,” has evolved. The original meaning was about fleecing rube customers of a little spare cash, and when said customers were fleeced, moving on to the next venue, much like locusts, but not nearly as destructive, because the locals were not being left destitute. But the point is, it was a mass market being accessed one venue at a time, sweeping across the country. In the market described in this thread, the pool of suckers is vastly reduced, because it is now suckers with very large amounts of discretionary income, who are suckers because they don’t understand what they are buying. In fact it is a reasonably accurate generalization to say that people who understand enough about the subject matter to not buy into the marketing also wouldn’t have the money to buy into it, if they were so inclined. Because it is a rarefied group of suckers, they must be accessed universally in a very low-cost manner. So instead of putting these products in retail shelves across the nation, I’m guessing that the major thrust of the marketing is totally via the internet, and that while a few high-end stores in a few very large cities may carry samples, most folks are going to be buying these products direct from the manufacturer, and that is one reason the return polices are generous. And the blogs act as virtual meeting grounds for the suckers, where they can can bask in the herd mentality, congratulating each other on their fine taste and breeding.

Subject: Re: [PSES] Fuses can affect performance other than safety! I recommend reading the ad copy from Audioquest. Some of the more interesting claims are for their HDMI cables, but their web site is full of interesting reading. http://www.audioquest.com/hdmi/ <http://www.audioquest.com/hdmi/> “All audio cables are directional. The correct direction is determined by listening to every batch of metal conductors used in every AudioQuest audio cable. All signal conductors controlled for digital-audio direction in AudioQuest HDMI cables, and care is even taken to run the conductors used in the Audio Return Channel in the opposite direction to ensure the best performance for that application. Arrows are clearly marked on the connectors to ensure superior sound quality.” If you are wondering about the price, Amazon has the “Diamond” level HDMI cables available for the low price of $13,500 <https://www.amazon.com/AudioQuest-Diamond-52-49-Braided-Cable/dp/B00IL3TZSQ> .
