British manufacturer Wilson Benesch unveiled a new tonearm for turntables at the High End Audio Fair in Munich before the summer holidays. The new tonearm is called the Graviton Ti , and according to its designers, it’s nothing less than the most advanced tonearm ever designed. Now that more photos and technical information are available, we’re taking another look at Wilson Benesch’s new tonearm.
Wilson Benesch Graviton Ti
According to the manufacturer, the Graviton Ti is designed for the discerning audiophile and true music lover, setting a new benchmark in analog performance. The Graviton Ti features, among other things, a graphene-reinforced carbon fiber arm tube combined with biomimetic titanium structures, developed through an advanced manufacturing process. According to the designers, every aspect has been meticulously considered, resulting in absolute precision and mechanical neutrality.
Proof of this attention to detail is the so-called Stage One, a uniquely elegant solution unparalleled in tonearm design. The tonearm wire runs vertically outward over the pivot point and enters a shielded chamber with less than an inch of exposure. This eliminates all mechanical force from the wire and protects the signal at its most vulnerable point. But there are even more unique technical discoveries incorporated into the Graviton Ti.
Wilson Benesch Graviton Ti: Quad-Helix Carbon Fiber arm wall
The Graviton Ti’s arm tube is constructed from a single-piece carbon fiber structure hand-laid by Wilson Benesch engineers featuring a complex quad-helix fiber orientation and an integrated carbon fiber headshell.
The hyperbolic shape optimizes stiffness and mass distribution for maximum performance without material redundancy. The arm tube is reinforced with a graphene-reinforced matrix and selective placement of UD fibers for optimal damping and energy transfer. Internally, Rohacell and viscoelastic materials provide industry-leading damping. The result is the stiffest, most damped tonearm tube ever designed. If nature were to grow a tonearm, this is what it would look like.
Wilson Benesch Graviton Ti: biomimetic titanium counterbalance architecture
The Graviton Ti features a titanium counterbalance system. This architecture, developed over years of R&D, is structured in hollow, tiled, and solid sections, each carefully optimized for its role within the system. It begins with a lightweight, hollow shape that follows the helix of the carbon arm tube, creating a large surface area for seamless energy transfer while minimizing mass. Moving below the pivot to maintain the lowest possible center of gravity, the structure is internally tiled, absorbing energy through anisotropic lattice geometry, according to Wilson Benesch.
The structure transitions to a solid shape at the bearing surface, delivering maximum stiffness where it’s needed most. This adaptive architecture minimizes mass, maximizes damping and stiffness, and defines a shape that is entirely determined by its function.
Wilson Benesch Graviton Ti: kinematic bearing system with zirconium elements
The Graviton Ti features a precision-engineered kinematic bearing, developed from the acclaimed ACT One Tonearm. Its core consists of ultra-hard zirconium bearing elements, selected for their exceptional surface finish and ability to reduce friction under extreme Hertzian contact loads. These properties guarantee near-static conduction and ultra-smooth tracking of the record groove.
A hybrid tri-point bearing arrangement with two zirconium balls and one conductive steel ball provides both mechanical stability and effective electrical grounding. This combination minimizes noise and distortion, allowing the tonearm to follow the groove completely neutrally and without interference.
When mounted on a Wilson Benesch turntable, the Graviton Ti integrates the Piezo VTA system for micro-adjustable tracking height, along with a damping reservoir for further resonance control. Together, these features create a bearing system of remarkable precision, refined by decades of British engineering innovation.
Wilson Benesch Graviton Ti: Stage One Over-Arm Interface
Stage One, originally developed for Wilson Benesch’s System Turntables (the GMT One and Prime Meridian), redefines the relationship between the tonearm and the signal chain. The over-arm design allows the tonearm wire to extend vertically above the pivot point into a copper-shielded chamber, with less than an inch of bare cable exposed.
This eliminates mechanical stress on the bearing and prevents torsion or drag on the signal cable, an often overlooked shortcoming in traditional designs. With nanometer resolution, even the smallest external force can compromise accuracy.
Stage One is now designed to integrate with select turntables from other manufacturers, offering its unique, elegant, and effective solution to a wider range of discerning audiophiles. By maintaining mechanical neutrality and signal integrity at the most critical point, it ensures that music remains untainted, uncolored, and absolutely true to life.
Wilson Benesch Graviton Ti: the Finn
Finally, the Fin is a precision-engineered titanium bow, developed exclusively for the connection between the Tessellate Ti cartridge and the Graviton Ti tonearm. The shape, crafted using Selective Laser Sintering (SLS), combines minimal mass with maximum stiffness, ensuring superior mechanical stability at the critical connection point.
This isn’t a conventional mounting system. By replacing traditional bolts and washers with a structurally integrated component, the Fin creates a multi-material damping pad, allowing the cartridge and tonearm to form a single, cohesive, high-quality assembly. For those seeking the highest resolution from their analog system, the Fin is a defining design element.
Wilson Benesch Graviton Ti: modular system compatibility
The Graviton Ti tonearm is designed with modularity in mind. Originally developed for Wilson Benesch system turntables, a custom armboard has now been developed to support installation of the Graviton Ti on other leading turntables from other manufacturers.
With its 12-inch length and highly refined mechanical architecture, the Graviton Ti is ready for integration into a wide range of high-end analog systems. Additional armboards will be developed to support other platforms.
Wilson Benesch Graviton Ti tonearm: price and delivery information
The Graviton Ti tonearm is available to order now, with first deliveries expected in the fourth quarter of 2025. The suggested retail price is €39,500 for the standard matte titanium finish. Other finishes are available for an additional fee.
