Mobile Fidelity Super HeavyWeight Champion Noise Dissipation Record Weight at Vinyl Sound Toronto Canada

The Super HeavyWeight Champion is a premium noise-dissipation record weight from Mobile Fidelity (USA), developed in collaboration with Mike Latvis of Harmonic Resolution Systems (HRS), and available at Vinyl Sound in Toronto, Canada. Engineered specifically for mid-to-high-mass turntable platters, it goes far beyond the coupling function of a conventional record weight by actively draining groove, motor, and bearing noise away from the stylus during playback. Weighing 495 g and machined from billet 6061 aluminum with a proprietary HRS polymer core containing eight separate damping chambers, the Super HeavyWeight Champion delivers blacker backgrounds, improved clarity, enhanced microdynamics, and greater bass impact. Its non-threaded drop-on design and label-safe soft polymer underside make it immediately compatible with virtually any spindle-equipped turntable platter of sufficient mass.

Beyond Coupling: Active Noise Dissipation via HRS Polymer Technology

The vast majority of record weights on the market perform a single mechanical function: pressing the LP against the platter to improve contact and reduce record warp. The Super HeavyWeight Champion performs this function and then goes considerably further. Developed with Mike Latvis of Harmonic Resolution Systems, a company whose isolation and damping platforms are used in some of the world's most demanding audiophile and professional audio installations, the Super HeavyWeight Champion houses a proprietary ultra-dense polymer formulated specifically for its noise-absorption characteristics. This polymer is precision-molded into eight separate internal chambers within the body of the weight, maximizing the surface area of the damping material in contact with the mechanical signal chain. The result is a weight that actively absorbs and dissipates groove noise, motor vibration, and bearing resonance before they can travel back up through the platter and into the stylus, reducing the noise floor and allowing previously obscured low-level musical detail to emerge.

Billet 6061 Aluminum Shell, Precision Balance, and Label-Safe Underside

The outer shell of the Super HeavyWeight Champion is machined from billet 6061 aluminum, the same alloy widely used in high-tolerance aerospace and audio applications for its combination of rigidity, machinability, and resistance to resonance-inducing flex. The black anodized top cap features a laser-etched MoFi logo, and the overall shape is designed for easy, confident gripping during placement and removal. The precision transfer molding process used to integrate the HRS polymer into the aluminum shell ensures exact alignment and balance, so the weight spins concentrically on the spindle without introducing rotational imbalance. The underside is finished in soft polymer that makes firm contact with the label area of the LP without risk of damage, scratching, or adhesion. A bamboo storage box is supplied for safe keeping between listening sessions.

Key Features

Frequently Asked Questions

What is the Mobile Fidelity Super HeavyWeight Champion?

The Mobile Fidelity Super HeavyWeight Champion is a 495 g noise-dissipation record weight co-developed with Mike Latvis of Harmonic Resolution Systems (HRS), featuring a proprietary eight-chamber HRS polymer core inside a billet 6061 aluminum shell. It is engineered for mid-to-high-mass turntable platters and goes beyond conventional record weights by actively draining groove noise, motor vibration, and bearing resonance from the playback chain. Available in Toronto, Canada through Vinyl Sound.

How does the Super HeavyWeight Champion differ from a standard record weight?

A standard record weight couples the LP to the platter to reduce warping and improve contact uniformity. The Super HeavyWeight Champion does this and additionally functions as a noise-dissipation device, using a proprietary HRS polymer distributed across eight internal chambers to absorb and drain groove noise, motor vibration, and bearing resonance before they can travel through the platter into the stylus. The audible result is blacker backgrounds, improved microdynamic resolution, enhanced clarity, and greater bass impact that a simple coupling weight cannot achieve.

What turntables is the Super HeavyWeight Champion compatible with?

The MoFi Super HeavyWeight Champion is optimized for turntables with mid-to-high-mass platters, generally those with a platter mass of approximately 5 lbs or heavier. Its non-threaded drop-on design makes it compatible with any standard spindle-equipped turntable platter in this category, including high-mass designs from manufacturers such as VPI, SME, Clearaudio, Brinkmann, and similar premium turntable brands. It is not recommended for lightweight suspended-chassis turntables where the combined weight of the record and the weight may exceed the design limits of the platter bearing or suspension.

What is Harmonic Resolution Systems and why does the collaboration matter?

Harmonic Resolution Systems (HRS), based in Buffalo, New York, is one of the most respected names in audio isolation and vibration management, producing equipment racks, isolation platforms, and damping products used by audiophiles and recording studios worldwide. Mike Latvis, the founder of HRS, brings decades of expertise in the science of mechanical noise absorption to the Super HeavyWeight Champion. His involvement means the HRS polymer formulation and eight-chamber internal geometry are not generic damping materials but are engineered specifically for the noise frequencies and mechanical characteristics of vinyl playback, resulting in a measurably and audibly lower noise floor during use.

Will the Super HeavyWeight Champion damage my LP labels?

No, the Mobile Fidelity Super HeavyWeight Champion will not damage LP labels. Its underside is finished in soft polymer rather than bare metal, ensuring that the contact surface between the weight and the record label is non-abrasive and non-adhesive. The weight can be placed and removed safely on any standard LP without risk of scratching, tearing, or leaving residue on the label area.

Where can I buy the Mobile Fidelity Super HeavyWeight Champion in Toronto or Canada?

The Mobile Fidelity Super HeavyWeight Champion is available in Toronto and across Canada through Vinyl Sound, an authorized Mobile Fidelity dealer in Toronto, Canada. Vinyl Sound carries the full MoFi Electronics accessories lineup, including both the Super HeavyWeight Champion and the standard Super HeavyWeight, and can advise on the appropriate model for your specific turntable and platter mass.

How does the Super HeavyWeight Champion compare to the standard Super HeavyWeight?

The Super HeavyWeight Champion and the standard Super HeavyWeight share the same fundamental HRS polymer noise-dissipation technology and non-threaded drop-on design, but the Champion is heavier and features eight separate internal polymer chambers compared to the standard model's construction, increasing the total damping surface area and making it better suited to mid-to-high-mass platters. The standard Super HeavyWeight is designed for universal turntable compatibility including lighter-platformed designs, while the Champion's greater mass and expanded polymer core deliver a higher level of noise reduction on turntables whose bearings and motors can comfortably accommodate the additional load.
