SUBSTANTIAL VIBRATION CONTROL AND NOISE REDUCTION FOR ANY AUDIO COMPONENT
Developed in coordination with the acoustic experts at Harmonic Resolution Systems, Mobile Fidelity Ultra Low Noise Feet provide substantial vibration control and noise reduction for any component under which they are placed. Featuring an outer housing comprised of milled aluminum, the 1.578-inch-tall feet (1.37 to 1.45 inches when loaded) dramatically lower the noise floor across the entire audio band all the while doing no harm in the frequency and phase domain, allowing you to hear more detail, nuance, texture, tone, focus, and clarity from all of your music. All you need to do to experience the benefits is place the component on top of the feet and use the provided level to check that everything is balanced. Then, sit back and listen. You will notice less hardness, dryness, brightness, and much more of what you should be experiencing. Ultra Low Noise Feet work with turntables, DACs, preamplifiers, CD players, power supplies, bookshelf speakers, and more.
“There are easily heard improvements – an initial sense of refinement progressing towards a lower noise floor uncovering more detail, a cleaner presentation with seemingly extended bandwidth, a more expansive soundstage, and quite extraordinary image specificity. The feet are [staying]. Enough said.”

ULNF24-32 Ultra-Low-Noise Feet support between 24-32 pounds (specifications for four feet)
Vibration Is the Enemy to Great Audio
One of the challenges in audio is the vibrations created by your speakers, which cause components to vibrate. Such vibrations raise your system’s noise floor, obscuring details in the recording. The effects of vibrations occur in all components. If your system sounds unnatural, dry, hard, bright, and/or missing detail, it can be due to lack of proper vibration control.
Ultra Low Noise Feet Effects and Advantages
Mobile Fidelity and Harmonic Resolutions Systems spent three years testing and developing Ultra Low Noise Feet to create a low noise floor across the entire audio band to deliver a quiet background; do no harm in the frequency and phase domain; supply consistent performance improvements across component and environment settings; and offer a high price-to-performance ratio. Careful selection of materials through design, measurement, and listening resulted in the final product. Installing ULNF under a component makes it effectively isolated and removes chassis noise, giving the playback system quieter backgrounds and a more immersive sound.
Applications and Recommended Use
ULNF work on a majority of gear, including turntables, DACs, CD players, preamplifiers, power supplies, bookshelf speakers, and more. Each set is available in three different weight ranges for optimum performance with your components or bookshelf loudspeakers. The listed weight equals the total amount a four pack can support. We recommend a minimum of four feet per component. More feet can be added to support additional weight or in the case a component has challenging weight distribution.
