GutWire Ultimate Grounding Cable

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. 

I am sure the Gutwire Ground cables are very good, but after reading this thread, I became very intrigued by the "concept".

I ended up building a couple of my own cables, using decent AC plugs, NOS WE 10ga wire, connected from the ground pins to the pin 1s of a couple of Neutrik XLR connectors.  I put one on my DAC (battery powered), and one on my preamp.  I already thought my system was very quiet, but this tweak, while cheap, has a very positive affect on my system. Biggest improvements for me were in bass articulation and definition, and midrange clarity.  I also saw some improvements in soundstage size and airiness.  Yup, my DIY grounding cables will be staying in the system!
