Spiral Groove today announced the availability of its new top of the line Spiral Groove SG1.2 turntable, which incorporates a host of upgrades from the previous SG1.1. The SG1.2 features a new platter, isolation feet, damping material and various other parts and, according to Spiral Groove, an improved magnetic platter levitation system to deliver significantly improved sound quality and performance. And, the increased weight of the new platter adds more impact to the bass and a bit more focus and depth to imaging.

The SG1.2’s new turntable feet, based upon the design of Spiral Groove’s Strange Attractor isolation feet, and the 20 pounds of additional weight provided by the upgrades contribute to the turntable’s improved isolation and reduced noise floor.

The SG1.2 is engineered using Spiral Groove’s Balanced Force Design approach, aimed at achieving the most elegant equilibrium of materials, performance, function, manufacturability and beauty.

The body of the SG1.2 utilizes two separate constrained layer platforms, separated by elastomers that mechanically decouple the two assemblies, forming a dense, rigid and well-damped, non-resonant platform to which the working parts of the turntable can be precisely mounted and isolated from one another.

The SG1.2 offers electronically selectable 33-1/3 and 45 rpm speed control. The low voltage/high-torque AC synchronous motor is decoupled from the rest of the turntable for exceptionally quiet record playback. The inverted sapphire disc/hardened steel bearing and platter assembly is mounted in a manner that allows the platter to rotate freely without flexure or noise, and the platter is driven at the fulcrum of the bearing for wobble-free rotation. The platter utilizes an oversize stainless steel drive ring to provide increased inertia and speed stability.

The tonearm mounting board of the SG1.2 is fitted with a stainless steel bayonet mounting system that is easily removed from the turntable with the push of a button, enabling multiple arm and cartridge combinations to be pre-set up and readily swapped and installed, with perfect alignment every time.

The Spiral Groove SG1.2 is currently available at a suggested retail price of $30,000. Here are all the detailed specs.
