Determining current flow to install "audiophile" fuses.

Geoff,

We’re in agreement that a shielded interconnect presents two variables which are potentially at odds with each other - the recommended directionality based on the which end the shield is grounded to vs. the grain orientation of the wire.

In bringing up shielded interconnects, I saw no mention of them earlier in this thread. It’s entirely possible my mind was numbed from reading it. I’ll take that as a hint that it’s potentially making me stupid and I’ll get back to my amplifier project before further damage ensues.

Thom, no harm, no foul. These guys beat you to the punch in this thread. The shielding argument is probably the leading argument used by skeptics of wire directionality. Followed closely by oxidation on contacts removed during test, placebo effect, expectation bias and a change in house AC voltage.

Atmasphere: "There can be reasons why a cable has directionality (mostly having to do with how the shield is constructed; this has nothing to do with fuses)."

Mapman: "Right my understanding is the reason the Monster wires are directional as indicated is because of the shield implementation. That’s pretty much the only reason that I have read of. My MIT wires have no indicators and I can’t say if it matters or not there. Fuses are a different story. Most high end audio fuse makers seem to leave a lot to the end listener’s imagination."

Georgelofi: "Yes you are correct some interconnects can be directional, ones that have +&- conductors with a shield, that’s only connected at one end, that end should be at poweramp.

But fuses are not shielded. And I still ask you or anyone else to post any manufacturers ad/doc that SAYS they are directional. "It’s all VOODOO" that you are promoting."

Cheers,

Speaking of amplifiers, assuming for the sake of argument that all wire is directional, imagine how much better Amplifier A would be if all internal wiring was connected with directionality in mind.  Point to point wiring, transformer wiring, capacitors, resistors, etc. And of course all cabling coming into and leaving the amplifier.

As a long time manufacturer of amplifiers and pre- amplifiers I hope you will share in detail the feedback your customers have conveyed to you concerning which fuses improved the sound and which did not.

So far all the comments we have received on boutique fuses have been positive. However for all those comments, not one of them has mentioned anything about directionality.  The feedback we have goes back about to about 2006 or so when the fuses seemed to move from the automotive stereo community to high end audio. 

If anyone looks at machina dynamica product lineup, one should understand that their products relate to audio the same way the fuse directionality does.

That looks like purchase from BB&B + story how it works = 20x profit.

For some fools works...

Math can solve most of science problems indeed.
