If ones' speakers are under 70 lbs., the GAIA III at $200 per set of four ($400 of course for a pair of speakers) is not TOO bad, I guess (assuming the loudspeakers are good enough to warrant advanced isolation). But the GAIA II will set you back $600 for 8, which is only 50 bucks less than a pair of the new Magnepan LRS speakers. And a set of the GAIA I is $1200, which will buy a pair of LRS' and subs.
But for $200, one set of the GAIA III might earn its' keep underneath a turntable, as Art Dudley just discovered.
