I like the Salamander Archetype, but I wish that Salamander still made the twin platform (double-wide) Archetype shelf.
Personally, I don’t pay much attention to vibration control except with a turntable and loudspeakers. You don’t want your turntable moving. And you want sand-fillable speaker stands. However, with electronics, the need for vibration control is exaggerated, IMHO
Listeners say they want sound equal to a live concert, but how do they control vibration at a live rock concert? The answer is that they don’t.
