If I thought I could hear the difference, I might be willing to spend the hundreds to thousands of dollars on the fancy vibration isolation gizmos but I'm pretty sure I wouldn't. I will say that putting those
E.V.A. Anti-Vibration Pad's under my subwoofer improved its sound immensely. Instead of the booming rumbling unmusical beast it was, it became tight and a pleasing companion to my Magnepan 1.7's. But putting those same pads under the 1.7's deadened the sound. It makes sense that tube amplifiers should have vibration isolation so I have them under that too. So I agree, listen and you may know, but some of us operate with more of a budget constraining our options. I'm getting the Tekton Moabs in 5-6 weeks and it will be interesting to try the EVA pads under them. Probably they will deaden the cabinet so I'm thinking of having a board or granite slab resting on them and the Moabs on top of that on spikes. That is a more realistic option for me than throwing $600 at the
Isoacoustics Gaia II Speaker Isolation footers.
