I have used spikes, Herbie's products, DIY, until finally biting the bullet and using IsoAcoustics products. The Gaia's blew me away in terms of sound improvement, which goes something like, cleaner bass, cleaner individual notes, smoother more dynamic, more natural, etc. I now have the orea's under my turntable, amp, dac, so, my recommendation is since you've already sunk a certain amount of money into the speakers, for a relatively small amount (comparatively) try their products (I think they offer 30 day trial). I would be very surprised if you'd send them back. I have found no negatives from their products.
