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!
