AudioPrism Ground Control Grounding Cables

Doug Blackburn has posted a review of the AudioPrism Ground Control Grounding Cables ($150/pair) at Ultra Audio. His conclusions:

There are many positive comments out there about AudioPrism’s Ground Controls, from reviewers and others who have already experienced them. My system, however, didn’t benefit from them, nor did a very different system. The Ground Controls indeed altered the sounds of both systems, but nothing I heard could be called a worthwhile improvement.
