Due to manufacturer policy and the bespoke nature of the Wilson Benesch GMT One System, pricing is not listed publicly and cannot be purchased directly through the site. Each system is built and configured based on your specific needs, and there are multiple variants available depending on your turntable configuration, isolation system, tonearm, and cartridge preferences
If you are a serious listener considering this investment, Michael will personally guide you through the options and can arrange a private demonstration for qualified clients. When you’re investing in a reference-level analog system, the process should reflect the same care and precision as the product itself.

We're an authorized dealer for every brand listed on this site, so your warranty is valid and fully supported. We're a real brick-and-mortar shop in Chestertown, MD with shelves of actual inventory, not a drop-shipper. Family-owned and run for three generations, since 1978.
Every GMT One System purchased through The Listening Room is made to order and personally delivered and installed by Michael Hoatson, our owner and analog system expert. This service is included in the price at any location in the United States. This includes:
This level of service is rarely seen in high-end audio today. You’re not just getting a product, you’re getting hands-on expertise from someone who understands what this system is capable of and how to make it sing in your environment.
For clients who wish to involve the Wilson Benesch factory team in their system installation, we can coordinate setup assistance with a factory expert for an additional fee. This optional service is available by special arrangement for those who desire the most technically involved presentation possible.
Wilson Benesch Greenwich Turntable
The Wilson Benesch Greenwich is the turntable that shouldn't exist at its price point. It shares the same ALPHA-OMEGA direct drive platform as the $300,000 GMT One, the same 15-inch OMEGA motor, the same quartz-referenced ALPHA electronics, the same GRAVITON Ti tonearm. What changes as you move up the GMT hierarchy is isolation and signal architecture, not the engine. The Greenwich gives you the engine.
Most direct-drive turntables use small motors that introduce cogging and torque ripple, the very vibration artifacts that vinyl playback was supposed to avoid. Wilson Benesch went the other direction. The OMEGA is 15 inches in diameter, the largest motor ever developed for a turntable, and it was built from scratch through a collaborative research programme with Sheffield Hallam University, backed by Innovate UK funding.
OMEGA employs a slot-less synchronous design with a circumjacent radial force architecture. In practical terms, that means the electromagnetic field is distributed so evenly across the motor that cogging is eliminated and torque ripple drops to nearly unmeasurable levels (0.001342 N.m RMS). The motor incorporates 21 precision-wound coils and 14 neodymium magnets arranged to create a uniform magnetic field that governs rotor synchronicity without requiring complex speed compensation algorithms.
A magnetic counterforce system reduces the effective dynamic mass acting on the Angstrom bearing, keeping Hertzian contact forces within safe limits while maintaining efficient energy transfer. The result is a drive platform that spins the platter with a level of stability and silence that belt and idler systems simply cannot match.
The ALPHA Drive is the brain of the GMT platform. It generates quartz-referenced multi-phase sine waves through three super-linear Class A amplifiers, delivering precisely controlled current to each motor pole. This approach ensures exceptionally stable rotational behavior and accurate speed control without relying on complex feedback correction loops that can introduce their own artifacts.
All GMT turntables ship with a dedicated tablet preloaded with the GMT Control App and a preconfigured router (the system does not connect to the internet). The app provides a clean interface for selecting playback speeds (33, 45, and 78 RPM), starting and stopping the platter, and performing fine speed trim adjustments in 0.01 RPM increments.
Available as an optional upgrade for the Greenwich (included standard on the Prime Meridian and GMT One), the Piezo VTA Control System adds remote-controlled vertical tracking angle adjustment with nanometre-scale resolution. Users can store and recall multiple VTA positions directly within the GMT Control App, which means switching between cartridges or compensating for different record thicknesses takes seconds rather than minutes. The system also manages automatic tonearm lift when the platter stops.
The Greenwich is configured for one Wilson Benesch GRAVITON Ti armwand, a kinematic-bearing design that provides three-point location for zero Brinelling and optimal energy transfer between two dissimilar materials. The bearing is engineered for quick armwand changes in under a minute, and the tonearm accommodates any cartridge weight.
For a fully integrated signal path, the Greenwich pairs naturally with Wilson Benesch's TESSELLATE Ti-B, TESSELLATE Ti-D, or TESSELLATE Ti-S cartridges. The STAGE One signal architecture, integrated within the Greenwich armhub, keeps the lead-out wire as short as possible to minimize signal corruption.
The GMT Collection is designed as a unified platform. The Greenwich, Prime Meridian, and GMT One all share the same ALPHA-OMEGA drive foundation. What evolves through the range is isolation and signal routing: the Prime Meridian adds FrACTaL Damping technology in the chassis and includes the Piezo VTA Control System as standard, while the GMT One adds the LeVeL pneumatic isolation system with microprocessor-controlled self-levelling.
This means Greenwich owners enter the platform at an accessible point and can upgrade progressively, adding the optional R1 Carbon Rack for optimal component placement, the Piezo VTA Control System for precision tracking angle control, or eventually upgrading to a Prime Meridian chassis to gain FrACTaL Damping. The core drive platform and associated system components carry forward through each step.

The Greenwich's heart is undoubtedly Wilson Benesch's impressive Omega Drive system. It is an innovative direct-drive design that integrates the platter directly into the motor. Omega Drive was developed through collaboration between Wilson Benesch and Sheffield Hallam University and supported by Innovate UK funding. At 15 inches in diameter, this is claimed to be the largest motor ever developed for use in a turntable.
