KRONOS SPARTA 

Unique to behold, the Sparta is essentially two complete turntables, each including a skeletal,

metal-framed plinth fabricated of solid aluminum boards with phenolic inserts, one situated immediately above the other,

both hang freely from the same patented, four-post, pillar suspension system.

Occupying a space some 20 inches wide, 14 inches deep, and 11 inches tall, and weighing 70 pounds,

the Sparta comes in at less than half the weight of my reference Redpoint Model D, yet with a similar overall footprint.
