Nordost Sort Kones Specs "The Sort Kone is a directly coupled and mechanically tuned resonance control device, using a sophisticated new approach to the problem of supporting sensitive electronics." - Nordost Why do we recommend this device, and for what component? Unlike spikes, the Sort Kones are used facing up as shown in the picture. A set of 3 is recommended for one component, and 1 should be put underneath the power transformer where most weight is.Suited for sources and preamps. The Sort Kones floats the component and dissipates energy from the inside. Certain frequencies will stop jumping around, soundstage is slightly more organized.*This is a device for fine-tuning, it makes an obvious improvement but not dramatic. Components that don't have the most solid chassis work in particular benefit the most. There are 4 models available, this is our pick for reasonable cost and result.*
