Nordost Sort Kones BC

I have enjoyed these under my electronics. They work quite well.

The price is $95/cone. I have 12 for sale.

From the Nordost website: "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. 

Whereas most equipment supports are referred to as Isolation Devices, this actually completely misunderstands the nature of the problem. The most harmful mechanical energy doesn’t enter the equipment from outside; it’s generated internally by the audio circuits and their power supplies. Transformers, power supply capacitors, even the active devices themselves, all vibrate as they operate – and those vibrations occur right where the fragile signal is, creating timing errors that smear and distort the music. The Sort Kone is designed specifically to deal with this threat to audio fidelity.

Sort Kones provide a “blacker” background to your music. With it comes greater focus, instrumental color, depth, transparency and dynamic range. Your system will sound more natural and more lifelike, your music more lively and engaging, the musicians like better musicians – simply because you’ll finally be able to hear the notes they’re playing, the way they play them and precisely when. So, release the hidden performance that’s lurking in your equipment.

• Three-part construction employs superior materials in a mechanically tuned configuration.
• Bypasses soft feet fitted to equipment to provide a direct mechanical ground path for internal energy.
• Can be used in triplets, quartets or even larger numbers.
• Height: 56mm

These cones have a bronze post and base elements combined with an upgraded ceramic coupling ball."

I have conservatively rated these as 7/10, though any damage is superficial and cosmetic only.  Boxes included for each Sort Kone.

Thanks for looking!
