MoFi Electronics Unveils UltraPhono Pro Phono Preamplifier with MasterPhono DNA

Experience pristine vinyl sound with MoFi Electronics’ UltraPhono Pro delivering masterful analog performance and flexible features.

When you're a vinyl lover, the joy of spinning records is all about capturing each sonic nuance, every crackle, and every note as the artist intended. MoFi Electronics, a name synonymous with top-tier analog sound, has just raised the bar with the introduction of their UltraPhono Pro phono preamplifier. This new preamp isn’t just another gadget—it’s a bridge between high-end audiophile performance and real-world accessibility.

From Analog Mastering Legacy to UltraPhono Pro

For over 40 years, Mobile Fidelity Sound Labs (MoFi) has been a standard-bearer in analog mastering, revered by purists for delivering warm, rich sound that digital often struggles to replicate. That legendary attention to detail is alive and kicking in MoFi Electronics' new UltraPhono Pro. Designed by industry veteran Peter Madnick, this preamp borrows the core design philosophy and performance DNA from their flagship MasterPhono model—but with a refined, more accessible price tag.

Madnick’s goal was simple yet ambitious: craft a single-input phono preamplifier that captures the essence of vinyl without drowning users in complexity. The UltraPhono Pro’s ultra-low-noise circuit and premium component selection make it a serious contender for anyone who wants a high-fidelity front end without breaking the bank.

Performance That Packs a Punch

Don't mistake its streamlined design for simplicity. The UltraPhono Pro offers an impressive gain of up to 71dB, ensuring even the faintest needle movements translate into powerful sound. It boasts a wide and linear frequency response ranging from 10Hz to 50kHz (±0.2dB), which means it captures the full spectrum of your vinyl’s magic, from deep bass to sparkling highs.

What’s more, its RIAA equalization is exceptionally accurate (±0.05dB), ensuring your records sound just right without unwanted coloration. The ultra-low noise floor lets the music emerge from silence, free from distracting hums or hiss.

Features That Speak to Vinyl Lovers

The UltraPhono Pro is built with the listener’s convenience in mind. Right on the front panel, you’ll find useful controls like mono mode, muting, a subsonic filter (perfect for tackling rumble from warped records), and dimmable faceplate illumination to fit your listening environment’s mood. Cartridge matching is thoughtfully flexible, too, with multiple loading options tailored for moving-coil cartridges and selectable gain settings for both single-ended and balanced outputs.

Key Features at a Glance:

• Single-input architecture inspired by the MasterPhono.
• Fully discrete J-FET and MOSFET input and output stages for clean, detailed sound.

Built to Blend, Made to Last
