Gutwire Perfect Grounding Cable


Haven't tried grounding boxes (e.g.,Entreq) because of their cost, but the Blue Moon award (Six Moons) winning Gutwire Perfect Ground cable at under $300 (see Gutwire's website) is worth trying.

The cable's single rca plug is connected to an unused input on my Pathos TT integrated and the AC connector is plugged into an unused wall socket. It isn't broken in yet, but there is an immediate improvement (reduction of the noise floor, etc.) consistent with the review.

Contribution of an audible and beneficial effect by way of shorter path to ground does seem unlikely. Appears to be something (easily?) tried out via DIY. I’m guessing only the ground pin of the AC plug is connected and that to the negative/ground lead of the RCA plug. Can’t imagine applying AC power to a component through an RCA jack and not doing some damage.  But then again, I'm no EE.
I didn't have a hum issue.  I have been reading reviews of grounding boxes (e.g., Entreq) for several years and wouldn't try them because of the cost.  Since the effects of the Gutwire cable described in the review sounded similar to the improvements reviewers have attributed to the Entreq boxes I gave it a try.

The cable can be attached to any unused input and can be ordered with rca, xlr, or spade connector (for components with a chasis ground connection).  There is no AC current involved - only the grounds on the input and AC connectors are wired.
Good post ghosthouse. Actually trying things before judging is the foundation of "the greater fool theory". ;)

This cable connects the ground of the circuit (via a phono plug neutral connection) to the ground pin of the Mains plug

Why? - Some circuit designs do not ground the neutral side of the circuit to the ground pin so there can be a noise buildup in that circuit

Grounding in this manner will ensure the neutral side of a connected circuit is grounded effectively - reducing the overall noise level

It provides a good solution to one aspect of the various noise related issues in a system

I have applied a similar DIY solution to components with  wal-wart power supplies or have a two pin plug (no ground) and it proved to be very effective

Now, all of my components have fully grounded circuits - so there is no need for this type of solution

When to use them?
- Check your component to determine if there is continuity between the neutral side of an input/output socket and the ground pin of the unit - if there is, there is no real need for one of these cables, but it will not be an issue if you still decide to use one

Gutwire make some very good power cables - this one goes one step further

Using this type of cable on every component will not create ground loop issues - if you have a hum while using this type of cable there is something wrong with a connected component - it is not the cable creating the issue

Wouldn't all of this be unnecessary if there was an industry standard on internal grounding of audio components?
