Speaker Cables

Diamond in the ruff?
Over the many years, gradually upgrading my system, the area of IC's and speaker cables have been the most challenging. I felt my current "garden hose" thick speaker cables, lay an opportunity. Being on a tight budget, I tried Morrow Audio SP3 speaker cables as some have suggested. Morrow Audio has a 60 full return policy. People, even though these are inexpensive cables, they absolutely blew me away in every respect over my esoteric cables.

Has anyone else tried these cables? What was your experience? I think these cables, in this price arena, are without peer.
