GutWire Ultimate Grounding Cable


With the recent reviews, and positive reports from a couple of members here, I decided to take the plunge and order one.

Like others I have been intrigued by the positive reviews for grounding blocks from various companies, but the prices are prohibitive. I decided to spend the extra $100 for the Ultimate over the Perfect as both reviews say it offers significant improvement. I am planning on plugging it into an unused RCA input on my Antique Sound Labs autoformer passive pre. I'll post updates after I get it, and have broken it in.

When I first got the UG, I briefly tried plugging it into the unused SPDIF output of my CEC TL-5 CD Transport, to see if it would make any difference there. I believe I heard an improvement. With the excellent results on my preamp, I decided to order another one for the CEC. Looking forward to hearing what it does.
If anyone wants to try something like the Ultimate or Perfect Ground, on the cheap ($50), I found the iFi Groundhog.

It has an RCA on one end, and a female IEC connector on the other, with only the grounds connected. That way, you can use whatever spare IEC power cable you have lying around to connect to the wall.




Interesting, I wonder if it will have the same impact as the Ultimate.  Just got my Ultimate and will plug it in tonight:)
I suspect the Ultimate offers more benefit, but the Groundhog may be a good way to try out the concept at a minimal cost.
Not much on the Groundhog online. They seem to market it as an audible hiss/noise killer, a slightly different tact than Gutwire.

At the CA iFi-sponsored area a couple people report the end-to-end measured resistance is 12-15 ohms and infer this might be a problem, but there is no response from iFi. I use the Gutwire and wonder how this is. In any case it sounds good.
