MoFi Electronics Ultra Low Noise Feet - 4 Pack - 8 Lb To 16 Lb Weight Capacity
Category: Accessories
Aluminum Isolation Feet Rated for a Component of 8 to 16 Pounds
MoFi Electronics Ultra Low Noise Feet are sold as a set of four with a bubble level. This is the ULNF8-16, rated for a component of 8 to 16 pounds across four feet: a phono stage, DAC, streamer, small preamp or light turntable.
Speaker energy in the room sets a component's chassis moving, and its stock feet do little about it. MoFi developed these feet with Harmonic Resolution Systems, an isolation specialist. Each is a milled aluminum housing, and the component rides on the feet rather than the shelf.
A Weight Range With a Floor as Well as a Ceiling
Fit, Load and Materials
The ULNF8-16 is rated for 8 to 16 pounds across four feet. MoFi publishes the range as a minimum and a maximum: below 8 pounds the feet are not loaded enough to work, and above 16 they need help. MoFi says to add feet for a heavier component or one with uneven weight.
Each foot is 1.578 inches tall in its milled aluminum housing and settles to about 1.4 inches under load. The top is a threadless grip surface, so the feet sit under the chassis without bolting on. Allow about an inch and a half of added height on a rack shelf.
MoFi makes the feet in three weight classes: 8 to 16, 16 to 24 and 24 to 32 pounds. This set is the lightest. The feet are made in the USA, and MoFi lists turntables, DACs, preamplifiers, CD players, power supplies and bookshelf speakers as intended uses.
Who Are the Ultra Low Noise Feet Best For?
- You own a phono stage, DAC or streamer of 8 to 16 pounds — four feet carry it inside MoFi's published range
- You want a machined metal foot rather than a polymer pad — the housing is milled aluminum and nothing about it ages or flattens
- Your component has to sit level — MoFi includes a bubble level, so a turntable or CD transport goes back on true
- You prefer American-made accessories — MoFi builds the feet in the USA
- Your component weighs more than 16 pounds — MoFi's 16 to 24 and 24 to 32 pound sets are the heavier rungs; ask us about them
How Do You Set Them Up?
Weigh the component and confirm it falls between 8 and 16 pounds. Set four feet on the shelf where the corners of the chassis will land, clear of the stock feet. Lower the component onto them and set the supplied level on top. Adjust the positions until the bubble centers, then listen.
Pairs Well With
What most Ultra Low Noise Feet owners shop next.
- Audio racks — a rigid, level shelf gives the pucks a firm grip
- Power conditioners — cleaner power for the gear you are isolating
- Isolation feet and cones — the other rungs for the rest of the rack
- Cables — the natural next upgrade for an isolated source
Frequently Asked Questions
How many do I need?
Four per component, and the set covers one. MoFi says to add feet for a heavier component or one whose weight sits mostly at one end, so a fifth foot goes under the transformer.
Which weight class do I need?
Go by the component's weight across four feet. This set covers 8 to 16 pounds. MoFi also makes 16 to 24 and 24 to 32 pound sets for heavier gear; a component right at 16 pounds belongs in the next class up.
Do they go under the stock feet or the chassis?
Under the chassis. The threadless grip top holds the component without bolts, and the stock feet hang clear. Nothing needs to be removed.
What is the level for?
MoFi includes a bubble level so you can check the component sits true on the feet. That matters most for a turntable or disc transport, where a tilt affects the mechanism.
