Something For The Fuse Guys ...

There are fuses, and then, there are fuses. 

I'm evaluating some prototype fuses that I received in the mail three days ago. 

Over the past few years, I've used fuses from five different manufacturers. The last three were the Red, Black and Blue fuses from Synergistic Research. Each one incrementally improved the sound of my system. My favorite so far was the SR Blue. 

The prototype fuses being evaluated presently raises the SQ beyond all of the others mentioned above. The major improvement to my ears is better tonal accuracy. Instruments and voices are more life-like. The noise is reduced allowing for a more solid 3-D presentation with the musicians more solidly presented on the sound stage. Overall, more information is fleshed out of CDs and LPs. 

The manufacturer, the price and the name of the prototype fuses will come later. I don't have the information thus far. My understanding is, if all works out, the release date is to be mid-October. 

Stay tuned ...

From Paul McGowen:

“The prototype amplifiers didn’t have output fuses. It wasn’t until we got to the production versions that we added them, and that’s when the trouble started. The production amplifier didn’t sound as good as the prototype: thinner, weaker, with less bloom and midbass strength, relative to the prototype. Why the two sounded so different was a real head scratcher.

When faced with such differences, you start removing any changes between the two until they sound the same. It didn’t take long before we discovered it was the damn output fuse.  Short it with a clip lead and the fullness of the music returned...

In the end we came up with a clever scheme. We took the feedback for the amplifier not from the amplifier’s output, but from the output of the fuse. Thus, the fuse was included in the amplifier’s corrective feedback loop, and the fullness returned to the music...

The point of the story is simple. Fuses matter. But why should they matter in the AC circuit? I don’t have a great answer handy. But we’ll look some more tomorrow.”

Paul’s favorite expression is, “I have no idea how it works but works it does!” Thanks, Paul. That was real helpful. 😬

A fellow A’goner is due here in a few minutes. He’s very familiar with my system. It will be a lengthy listening session today. Stay tuned ... we’ll see what he thinks of the prototype fuses.

PS: I didn’t know there was a "salesforce" involved here. I can hardly wait for my huge commission check to arrive in the mail.

One can set one's watch, clock, sundial, or even start a new entry in the Farmer's Almanac with the regularity that this topic comes up with. 👍

All the best,

Nah. The Farmer's Almanac was put out annually. The fuses, every two years or thereabouts. 
More to discover
