Determining current flow to install "audiophile" fuses.

Indeed whatcha'll arguin' for?
The "effort" had already been invested in directionality of fuse(s) to let you all fools know why fuses are so pricey. 
If you don't hear difference between directions and fuses, go to doctor OK?

Okay, I switched the fuse direction today and am listening. Details at 11...

My bugaboo:
IF fuses are directional, AND manufacturers know this, 
Then, Why can't they tell us which way to orient the fuse for most musical reproduction? As I said earlier, Pat as SMc, said to try them one way and reverse them later and see what sounded better. To my feeble mind, if these things are directional, then you must know which way is best without needing to switch things around.

Before reaching any conclusions, my suggestion is that you switch it back and forth a couple of times, and listen to the same recordings at precisely the same volume settings following each reversal. In other words, try to verify that the results are repeatable, and that any differences that may be perceived are not due to extraneous variables such as differences in warmup state, variations in AC line voltage and/or noise conditions that may occur at different times of the day or night, differences in contact integrity, etc.

I'll let you all debate fuses and directionality to your heart's content.  How you spend your time on this big rock we call Earth is none of my business.

Geoff - your comment: 

By the same token, reversing interconnects that were inserted randomly between components will improve the sound 50% of the time for the same reason. It’s a wire directionality issue. It’s why many boutique cable manufacturers have been putting directional arrows on their cables for twenty five years. Hel-loo!

doesn't belong in this conversation.  A large percentage of interconnects are shielded and should be plugged in according to the directionality that the manufacturer specifies.  No, I have not run a statistical survey of the percentage of cables that are shielded.

To those of you who don't know what this means from a hookup perspective, the outer shield is tied to the RCA ground at only one side.  The shield "floats" at the other side. 

The grounded side should be plugged into the source.  IOW, it should be plugged into the line stage side of an  interconnect that runs from a line stage to power amp(s), the phono stage side of a cable that runs from phono stage to line stage, etc..

In my experience, there is an audible degradation (noise) when you reverse the cable so the grounded shield side is plugged into the load side (i.e. the power amp in the above example).

Could wire be directional? Sure.  Could a cable manufacturer wire their interconnect such that the optimum direction (from a wire directionality perspective) is in conflict with the shield connection?  It's possible.

As I already stated I’m not referring to shielded designs. An example of an interconnect that comes with directional arrows but is NOT shielded is the ANTICABLES IC. The reason unshielded cables come with directional arrows is because the conductor itself is directional. ANTICABLES cables comprise only a (solid core) conductor with connectors. Thus, like fuses, and unlike shielded cables, they are perfectly symmetrical; so it must be the *wire itself* that produces directionality. Follow?

From Anti Cables website: "The ANTICABLES Analog RCA Interconnects use the same design concept as the award winning ANTICABLES Speaker Wires. They use only the materials needed (solid core wire and connectors). Those materials are of very high sonic quality, and unnecessary materials such as thick plastic jacketing are eliminated. They are simple, cost effective, and perform very very well..."
