Key Features
  • Pure Class A Tube Circuitry: Features four ECC83/12AX7 double triodes operating in pure Class A with no global or local negative feedback, ensuring low distortion and natural sound.
  • Precision RIAA Equalization: A passive RIAA equalization network, using high-quality resistors and capacitors, provides accurate frequency response across the entire audio spectrum.
  • Stable Power Supply: Equipped with a high-voltage power supply and precise voltage regulation, ensuring consistent performance and dynamic response.
  • Flexible Input Impedance Settings: Adjustable input impedance allows compatibility with Moving Magnet (MM) cartridges and high-output Moving Coil (MC) cartridges (above 2 mV).
  • Low Crosstalk and Noise: Symmetrical board design and advanced filtering minimize crosstalk and noise, enhancing overall sound quality.
About Unison Research

Unison Research, founded in Italy, has a long-standing reputation for crafting high-fidelity audio equipment that marries traditional craftsmanship with modern technology. Each product reflects their passion for music and dedication to producing equipment that delivers both sonic excellence and visual beauty. 

Design and Build

The Simply Phono preamplifier is designed with careful attention to detail, offering a refined sound that enhances your vinyl playback. The unique “ionic bias” configuration in the first gain stage reduces noise and distortion, while the passive RIAA equalization ensures accurate frequency response. This combination results in a dynamic and natural sound that stays true to the original recording.

The robust power supply is a key feature, providing more than 300V of stable, low-ripple power for consistent performance. Additional filtering and regulation circuits help minimize cross-talk and power supply rejection ratio (PSRR), particularly in the first gain stage, ensuring a clean and immersive listening experience.

Power Supply

The Simply Phono is a dual-chassis design: a separate external power supply connects to the main unit and is required for it to operate. Unison ships the Simply Phono with its power supply, and we offer it that way; we also sell the Simply Phono on its own if you already own the supply.
