Music making of the highest order.

Pure Fidelity “hybrid” design.
The plinth has a major impact on turntable sound. High-mass designs can have solid bass, but can sound dull. Low-mass designs can have good speed and dynamics, but often sound bright. Suspended decks can have good timing, but may lack bass. To combine the best elements of each design, Pure Fidelity’s founder, John Stratton created the ultimate “hybrid” approach, with intermediate mass based on an ultra-MDF plinth. The result is completely neutral sound. Bass is strong without being sleepy, while the highs are detailed without being bright. Fittingly, when each Pure Fidelity turntable reaches completion, John Stratton proudly signs the plinth.
Defeating vibration and resonance. Like a microphone, a phono cartridge works by converting mechanical vibration into voltage. Crucially, the cartridge not only picks up motion from tracking the record groove, but also unwanted vibration when sound from the loudspeakers impacts the turntable and the shelf it’s sitting on. The cartridge simply cannot distinguish between the music and unwanted vibration, which can degrade playback, damaging musicality and collapsing the soundstage. That’s why the Horizon and Harmony turntables embody an uncommonly thorough program to suppress resonance. The aluminum isolation platform, GAIA™ IV isolation footers, and ultra-MDF plinth all work together to produce music of such pristine clarity, it gives added meaning to our company name, Pure Fidelity.
6061 aircraft aluminum isolation platform.
A favorite choice for aircraft and automotive structures, 6061 aluminum alloy has superb rigidity, resisting deformation with a Young’s modulus of 10 million pounds per square inch. At a thickness of 3/4 inch (19 mm), this isolation platform provides extraordinary stability. And because the platform is separated from the ultra-MDF plinth by GAIA IV isolation footers, it maintains all the advantages of Pure Fidelity’s “hybrid” design.

Ruby bearing in a low-friction bronze shaft.
By the time it gets to your ears, the output of a moving coil cartridge can be magnified by a factor of 10,000 or more. So even minuscule imperfections in the turntable drive system can become audible issues. For this reason, even though we could purchase 100 steel bearings for the price of a single ruby bearing, we’re sticking with ruby. Ruby offers incredible hardness, with a Mohs scale of 9. (Only one precious stone is harder: diamond.) For similar reasons, we chose bronze instead of the industry standard brass for the bearing shaft. Bronze offers better durability, higher strength and a lower coefficient of friction. The end result of these two materials is a dead silent, near-frictionless drive system.
Conductor quartz locked speed control.
Custom AC synchronous motor. To satisfy our stringent requirements, the motor is quiet, stable and free from “clogging” – unwanted pulses of torque. We outfit our 12-volt AC synchronous motor with our own custom modifications that reduce clogging to the vanishing point.
Stainless steel pulley and two drive belts.
Large-profile aluminum/steel sub-platter. Pure Fidelity insists on a sub-platter combining 6061 aircraft-grade aluminum and stainless steel, both CNC-machined to a tolerance of 1/1000 inch. The result is near-perfect roundness and stable speed.

Acrylic Dust Cover
This is an optional accessory that fits all four models. It is made of ¼” thick acrylic with polished edges and has a metal Pure Fidelity logo embedded in the center . These are custom manufactured to our exact specifications and are specified as “ Museum Quality “ A very elegant solution to a common problem…… Keeping dust off your investment
Size; 19” wide x 16” deep x 8” tall
Custom configurations. You can configure the turntable with or without one of the tonearms we offer. You can select it with or without our Stratos MC cartridge.
Choice of lustrous finishes. Try as we might, our photography never quite captures the lustre, depth and romance of our available finishes. Choose from our two standard finishes: either Semi-Gloss Santos Rosewood or Dark Walnut. Or step up to a premium finish: High Gloss Quilted Maple or Piano Black.
Even the packaging is engineered. After optimizing every aspect of the turntable, we weren’t about to allow its performance to degrade in transit. That’s why we protect our products with extraordinarily robust and precise packaging. You can’t miss it when your turntable arrives, its subassemblies meticulously fitted into super-high-density foam carriers.
