iFi Audio - ZEN Phono 3
"Silence the Noise. Awaken the Groove. The Ultimate Balanced Phono Stage."
Product Overview
The iFi Audio ZEN Phono 3 redefines vinyl playback in its class, offering an impeccably quiet foundation that allows the true soul of your records to shine. Designed with trickle-down technology from ultra-high-end phono stages, it features a sophisticated, fully balanced, dual-mono circuitry that effectively banishes background noise and crosstalk. Whether you are spinning with a classic Moving Magnet (MM) or a demanding, low-output Moving Coil (MC) cartridge, the ZEN Phono 3 delivers unparalleled versatility with its vast array of precise gain settings and load impedance matching. Paired with an intelligent AI-driven subsonic filter that eliminates warp rumble without sacrificing low-end impact, this is the definitive analog upgrade for purists seeking pure, unadulterated musicality.

Key Features
- Universal MM/MC Versatility: Features four distinct gain settings (36dB, 48dB, 60dB, and 72dB) and customizable impedance loading to perfectly match any phono cartridge on the market.
- Intelligent Subsonic Filter: Utilizes proprietary technology to accurately identify and remove ultra-low frequency warp rumble without thinning out the driving bass frequencies of your music.
- Fully Balanced Circuitry: A symmetrical dual-mono design drastically reduces electrical noise and crosstalk, ensuring pristine channel separation and a pitch-black background.
- Audiophile-Grade Components: Built with premium Panasonic ECPU capacitors, custom OV-series op-amps, and a high-precision RIAA equalization network for class-leading acoustic transparency.
- 4.4mm Balanced Output: Offers a dedicated 4.4mm output for seamless, ultra-low noise integration into balanced preamplifiers, headphone amplifiers, or active studio monitors.
- Ultra-Low Noise Power Supply: The isolated internal 1.2MHz switching power supply operates far beyond the range of human hearing, protecting your delicate analog signal from mains interference.
