Beskrivelse
The first thing that distinguishes a Kronos turntable is its two equal mass platters, rotating opposite each other. We call this the dual platter counter-rotating revolution. It is a means by which the vibration inducing torque force, present in suspended turntables is eliminated. The result of this design is a suspended platform particularly well isolated from environmental and mechanical noise while maintaining unequalled stability. You can immediately hear the difference dynamic stabilization makes. No other turntable can offer its advantages.
Besides this, all of the Kronos turntables components keep other parasitic vibrations to a strict minimum. Our designs apply proven and solid technologies and use materials with complementary properties. Our groundbreaking DC computer controlled drive systems deliver outstanding speed control while remaining vibration free. Our proprietary hyper precision platter bearings rotate smoothly and are maintenance free and durable. Our plinths combine composite materials and metals so as to offer rigidity and minimize acoustical feedback. Our suspension is designed to be highly efficient as well as easy to set up.
Finally, with the help of recording engineers, our turntables have been fine tuned and optimized by comparing their test pressing playback performance to those of original master tapes. This comparative testing process has directed our work in achieving a neutral frequency response, natural timbres and transients and outstanding dynamics.
It is no wonder Kronos turntables are being used in award winning presentations all over the world. Kronos turntables are also chosen by music industry professional and by audio equipment manufacturers. But most importantly, Kronos turntables are providing enjoyment and pride of ownership to members of the audiophile community.

Kronos Sparta Turntable – The Absolute Sound

by Rick Becker | February 2016
In my show report I was a little more blunt than usual:
«No point in mincing words here. These are two of the greatest turntables available in the world today with their suspended, counter-rotating platters.… It is hard to imagine music sounding much better in this room than what I heard this year. It was a big room and it was very well set up; obviously one of the very Best Rooms at this, or any other show I’ve been to. The music moved me.»
