Audiopoints! Star Sound product. Used them on my Wilson MAXX speaker and they were a huge difference over stock spikes and discs that can be ordered will protect your floor no problem.
AVALON OWNERS...
What do you put under spikes of your Avalons? Mine ED's rest on a wooden floor and a 4mm cork mat and I put coins under spikes but I think there should be a better solution for this. Any suggestions?
