Thanks Tobes and Syntax. I brought this up because I had previously read someone's Audiogon comments claiming he heard both mounts and felt the Graham sounded better than the SME in several areas. In correspondence with Jeff Catalano at Highwater, he indicated no significant differences. I'm ready to go with the Raven One 'table and either the Phantom 2 Supreme or TW Acustic 10.5 arm. At the moment, I own the SME IV.Vi.
