I have Vandersteen 5A's on spikes as factory recommends. I tried Herbes gizmos ....absolutely ruined the sound. Each system is different and everyone should try them all to know for sure.
What your choice speakers with spikes or speakers with a vibration isolation device?
I am in the camp of vibration isolation. I think it makes sense that the less energy transfer into the floor goes into the air. I found these really cool magnetic isolation feet that I’ve never seen before. They are very affordable, the guys are from England.
