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.
