RGS92, while I can't directly answer your 6-23 post because I haven't actually listened to the speakers on both Skylans and Sound Anchors, I can suggest that if you do some more research on the web, including the Harbeth Users Group comments accessible from the Harbeth Home Page, you may find some information indicating that some Harbeth users have commented that they've heard a "ringing" when they used some metal stands with Harbeths. I think you'll also find that there are Harbeth owners have found both Skylans and Sound Anchors to work well with their speakers, which suggests that it would be hard to go wrong with either one.
If you decide, as I did for my Monitor 30s, to go with Skylan, you'll find Noel, the owner, to be very easy to deal with and very professional when giving advice and making promises about shipping dates.
