i use an active system under one of my turntables (you can see pictures on my system page), the Taiko Tana system, which includes the Herzan TS-140. but it does require a turntable that has zero self noise to be effective. so it won’t work for many turntables.

another great choice is the Stacore platform; which does not have the balancing issues of the Minus K. it takes the Vibraplane idea and puts it on Steroids.

i have 4 turntables; one of which is on the active system. i would choose the Stacore for the others if i could spend the money. here is a link to the North American importer.
