Yup, the GAIA first came to my attention via a quote from VPI’s Harry Weisfeld, who put them under his KEF Blade loudspeakers and loved the results. Others have also reported hearing benefits from their use, so I've been waiting for someone to compare the GAIA to the Townshend products (which have in the U.K. received the attention the GAIA are receiving in the U.S.), but finally gave up.
A set of the Townshend Pods for my loudspeakers are cheaper than the GAIA II (the speakers are too heavy for the III), so I’m giving them a try first. Based on my use of the Seismic Pods under my turntable, I expect to be pleased with the results. I’m sure the GAIA would also provide an improvement, but I’m not buying both just to find out!
