Floor protection from spikes

I have Joseph Audio Pearls 20/20...They weigh approx.150 lbs each...I have pine floors...I went with Gaia I and they really do isolate! They just tighten the overall sound... And they look cool as hell! Expensive 1200.00 USD...

I should have asked, what speakers do you have? My Pearls have out-riggers, I removed the stupid spikes (you would think for that kind of money JA would provide 2 options) and finished the tops of the Gaia's with a SS acorn nut...

Be careful using coins for such heavy speakers on hardwood. I use to own speakers that were about 150 pounds each and set the spikes on US pennies. When I moved I noticed I had penny size Abe Lincoln impressions on my hardwood floor.

Herbie's sells nice gliders for using under spikes.
Cheep too.
I would be wary of sorbothane as it might stain wood surfaces.
Another alternative is to get either butcher block or marble plinths made.
I know Richard Vandersteen swears by marble under his speakers.

I use Vibrapods under my Heresy IIIs, and did under my previous SIlverline Preludes also (the Preludes sat on maple butcher blocks).  I put stick-on felt pads under the "pods" so they can't mar the floor and I can micro move the Heresies or simply push them around when they get out of line.
