The MoFi UltraDeck concentrates on the mechanical fundamentals that determine what a cartridge can retrieve from a record. Its belt-drive layout uses an isolated 300 RPM AC synchronous motor and a stepped Delrin pulley for 33⅓ and 45 RPM playback. Decoupling materials limit motor vibration before it can travel into the plinth, platter and stylus, while the simple two-position pulley keeps speed selection direct and reliable.

The MoFi MasterPhono is an all-analog phono preamplifier designed with Peter Madnick for serious moving-magnet and moving-coil systems. Instead of forcing every cartridge through one input topology, it provides conventional voltage-mode inputs through RCA and XLR connections as well as a current-mode, or transimpedance, input for low-impedance moving-coil cartridges. That second approach presents a near-zero input impedance, allowing the cartridge’s current output to determine the signal while reducing sensitivity to cable capacitance and radio-frequency interference.

The MoFi UltraPhono Pro adapts the core architecture of the MasterPhono to a simpler all-analog phono stage. It is built around one single-ended RCA input, making it a practical choice for a system with one turntable and cartridge. The simplification does not eliminate the adjustments that matter: gain and cartridge loading sit on the front panel, where they can be changed quickly and repeated accurately.

The MoFi StudioSilver MC is a low-output moving-coil cartridge built in Japan around a nude MicroLinear stylus and boron cantilever. The stylus profile is shaped to make extended contact with the groove walls, helping it follow short-wavelength high-frequency information while distributing tracking force over a larger contact area than a basic elliptical tip. The rigid, low-mass boron cantilever transfers that movement to the generator with less stored energy.

MoFi Ultra Low Noise Feet are component supports developed with Harmonic Resolution Systems to reduce vibration reaching sensitive audio equipment. They are not universal rubber bumpers sold under an audiophile name. Each set of four is tuned for a defined equipment-weight range, allowing the internal isolation system to operate under the load it was designed to support.
