On Silverline 17.5, using EPOS metal stands ST12, the sound is very lively and the speakers disappear, with great transparency.
With Skylans, they sound less lively, disappear a little bit less well, and have a bit less going on.
BUT, there is something beguiling about the Skylan sound. Blacker backgrounds. More lyrical. Something about it just grabs your attention.
At least one of these two stands is very colored in sound!
(perhaps both?)
I can't say for sure that my experience with the metal EPOS stands will translate to the Sound Anchors. But I'll tell you that the difference is very substantial, with the metal EPOS sounding more like what I expect my cds (recordings that I'm very familier with) to sound like, but the Sklyan offering a take on the music that makes me smile.
I'm planning to play with both for the forseeable future, so I can experiment more (e.g. try lighter kitty litter instead of sand in the Skylan), and give each one more time to convince me it's the real thing.
Also I'll have fun demonstrating for skeptical visitors what a huge difference a pair of stands can make :)
I have a clear memory of past occasions where the component that sounded better to me at first did not wear on me as well as other choices. We shall see.
