Synergistic Red Fuse ...

I detest charlatans and snake oil salesmen too. That's why when I discover a product that works, like SR Black fuses and Herbie's tube dampeners, I like to spread the word.

"Consumer Fraud"...now that's MUSIC to my ears. At 66,with 50 years of record collecting excellent gear,and wise to this hobby, I detest "charlatans" and "snake oil" salesman.

really? Name two.

Frank,
Herbie's Audio Labs offers some very cost effective products in my experience.  A few years ago  I used their "Tender foot"  component footers and they were clearly  better than some more expensive alternatives I compared with them during that period. They were very good for not much money.

" However, as I’ve previously said in this thread what seems unexplainable is that upgrading to a specific fuse would be found to be sonically beneficial with the high degree of consistency that has been reported, among components that are completely different in design, that perform completely different functions, that are used in very different systems, that are powered by AC having very different voltage and noise characteristics, and in DC as well as AC applications. That continues to be a mystery as far as I am concerned."

I am making this post in good faith, because your tone and reasoned approach deserves a corresponding response. I do not have all the   answers but I believe there is an approach that may be helpful on a macro level.

Forget the fuse for a moment. A fuse cannot do the things you attribute to it. BUT A POWER SUPPLY CAN. All electronic devices, regardless of what they do , or whether AC or DC  powered, require and do have one or more power supplies. The Power Supply is the single most important component of all electronic devices. IT IS THE HEART OF THE DEVICE. It does not matter what the function of the device is. It does not matter whether the device is a preamp, power amp, CD player, DAC, Tuner, or a device used in commercial or industrial instrumentation.  It does not matter whether the AC has different voltage and noise characteristics. The Power Supply in an electronic device is like the heart in all animals. It does not matter whether the animal is a lion a mouse or an elephant. It does not matter if the animal lives in the North Pole or in the SAHARA desert. Optimum performance of all animals is dependent on a healthy and properly functioning heart.

The vast majority of power supplies contain one or more fuses. We know from experience that the performance of a Power Supply used in an audio product can be influenced by a fuse. How do we know this? We use the most accurate devices available. The human ears working in concert with the brain and nervous system to decode cognitive and emotional content (music)

But how can a fuse have such a salubrious effect on the music we hear? I do not know. I do not know anyone who does. Neither do I know what goes on at the sub subatomic level. Nor did Einstein. Yet what happens at the subatomic level is the basis of our stereo systems.

^^^  Charles ... I like to do a little at a time in order to gauge the improvement (or degradation) with each step in the "tweaking" process. I've been in the process of replacing the stock ARC dampening rings with Herbie dampeners. This is not a subtle change for the better. Its another ear opening experience. Herbie has a CD mat that just covers the inner ring of the CD. Its called the "Super Black Hole." It has some really good reviews, so I'll be trying that soon. And hey, Herbie's has a generous return policy too.
