Sorry, the MinusK is better than all of them. The reason is that it's horizontal resonance is just as low as it's vertical resonance. In other words you can hit your rack on the SIDE with a hammer and it will not bother the turntable. Yes, it is a bit more touchy to set up but once it is you can forget about it. You could always just buy a Dohmann turntable with the MinusK ready to go. The MinusK negative stiffness design is said to be better than any active device in terms of isolation.
Millercarbon, if you want to do it right you need to start working on your hanging turntable platform as described above. If you get it right it will work better than anything you are doing now. Promise:)
Mike L, The Stacore has little if any lateral compliance plus you need to keep it pumped up. The MinusK requires none of this. Both it's horizontal and vertical resonance are less than 2 Hz. They also make a low profile version now which elevates the turntable 2-3 inches only. The only real downside I can see is that the platform is ordered based on turntable weight. If you were to change turntables it might not work.
