OAD Ultrafidelity - UP1 Reference - Phono Preamplifier Review: A New Benchmark in Vinyl Fidelity
The OAD Ultrafidelity - UP1 Reference - Phono Preamplifier Review kicks off our exploration of what is arguably the most accomplished phono stage to emerge in recent memory. Built on the foundation of ultra-low noise MC/MM circuitry and a fully isolated power architecture, the UP1 Reference elevates analogue playback to new heights, delivering unprecedented clarity, dynamics and musicality.

Design and Build Quality
Milled from a solid block of aluminium, the UP1 Reference’s chassis not only ensures exemplary EMC shielding but also forms a robust foundation for the five independent power supplies within. Replacing conventional low ESR capacitors with high-performance solid polymer capacitors results in a power reserve that exhibits higher ripple current tolerance, lower ESR and stable capacitance across all operating temperatures—guaranteeing longevity and rock-solid stability.

Ultra-Low Noise MC/MM Circuitry
At the heart of the UP1 Reference is a fully discrete, dual mono amplification topology tailored for both Moving Magnet and Moving Coil cartridges. With a gain range from 40 to 80 dB in 5 dB increments and THD as low as 0.004 % (1 kHz), the phono preamp provides world-leading gain flexibility without inviting noise. A-weighted S/N ratios exceed 113 dB for MM and 93 dB for MC, ensuring even the most delicate vinyl passages emerge free from hiss or hum.

Customisation and Cartridge Compatibility
No cartridge need be left behind: the UP1 Reference features two DIP-switch banks offering eight input impedance presets (22 Ω to 47 kΩ), additional capacitance for MM and moving iron selection, and gain settings from 40 dB to 80 dB in 5 dB steps. Cartridge loading and gain can be dialled in on the fly—no soldering or additional modules required. High-current line drivers effortlessly drive long interconnects or challenging downstream loads.
Accurate RIAA Equalisation
Implementing precision RIAA correction filters (75 µs, 318 µs and 3,150 µs single-pole networks) with ±0.1 dB linearity across 20 Hz–20 kHz, the UP1 Reference restores the original recording’s tonality with forensic accuracy. Whether your records demand deep, controlled bass or airy top-end extension, this phono stage preserves the integrity of the groove with unwavering fidelity.
Who Should Consider the UP1 Reference
This is the go-to phono preamplifier for the serious audiophile, the vinyl enthusiast and the professional seeking reference-grade performance. If you crave:
- Pinpoint imaging and wide soundstage realism
