The ZEN Phono is a wonderful enhancement to your vinyl setup. It will max out every MM/MC cartridge.

Unlike any other entry-level phono stage. The ZEN Phono has:

  • MM/MC from 36dB >72dB gain. Super-silent noise floor -151dBV
  • Precise RIAA with Balanced output, performance comparable to +$1k phono stages 
  • AI sub-sonic filter. Addresses warp without eliminating bass or causing phase issues

Flagship phono amplifiers create their own power supply off the mains, like a mains regenerator. This is fundamental to a well-designed phono stage. Without this, it will struggle to amplify the signal without added noise. This is why phono stages ‘hiss’ so annoyingly.

Unusually, the ZEN Phono has its own high-tech clean power supply. It creates a 1.2MHz power supply (20,000x mains frequency of 60Hz). In this circuit, a 10uF filtering capacitor = 200,000uF at lower, audible frequencies. With serious levels of noise filtration, it performs at the level of well-designed LC filtering circuits as found in classic tube amplifiers. Further, located on its own ‘island’ PCB, it is isolated so there is no noise pollution of the analogue stage.

Just super clean +/- 12V DC.

Measured EIN (Equivalent Input Noise) is -151dBV. It is 20dBV quieter than some Stereophile Class A+ phonos which are -131dBV.
