Nordost Sort Kone BC and AC cones

I have three sets of these Nordost Sort Kones. The listed price is for one set (3) of the BC style. I two total sets of BC and one set of AC which are $150 for that set.

The Sort Kone is a sophisticated, directly coupled and mechanically tuned device which channels vibration away from the chassis, allowing the internal components to operate more effectively. Sold individually, Sort Kones may be configured in a number of ways to properly "sort" out your components. We generally recommend starting with three Sort Kones in a triangle configuration and adding more as necessary.
