The iFi Audio Zen Phono is the preamp that will help you enhance your vinyl gear and maximize the performance of each MM/MC cartridge.
Flagship phono amplifiers create their own power supply from the mains, like a mains regenerator.
This is essential for a well-designed phono stage. Without this, you will have difficulty amplifying the signal without additional noise.
The ZEN Phono has its own high-tech clean power supply. It creates a 1.2MHz power supply (20,000x 60Hz mains frequency). In this circuit, a 10uF filter capacitor = 200,000uF at lower audible frequencies.
With serious levels of noise filtering, it performs at the level of classic LC filtering circuits found in classic tube amplifiers.
The ZEN Phono has some really nice audio components that back up the fabulous circuit design that has leaked from its ultra-fidelity AMR PH-77 and iFi iPhono siblings.
