This is also on my list. Nothing negative about these cables or this idea of grounding on the web, except of course, the few Debby Downers with closed minds that post on this site.
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.
