Zen Phono 3 boasts futuristic features unlike any other entry-level stage:
- MM/MC with 36-72dB gain range
- Independent loading adjustment
- Super-silent -151dBV noise floor
- Precise RIAA with balanced output
- Intelligent subsonic filter
- High-tech 1.2MHz clean power supply
Since the very first iPhono launched in 2012, we have used our own in-house Subsonic Filter. As there is only minimal vertical modulation remaining at very low frequencies with an actual cut LP that is playable, we know that “vertical modulation” at low frequencies must be warp.
By understanding fully how LP’s are cut and replayed, it is possible to filter record warp strongly without at the same time attenuating low bass or adding group delay.
TDK C0G (Class 1 ceramic) capacitors offer high stability and low losses for resonant circuit applications.
Getting ever closer to the theoretical ideal of pure, frequency-constant capacitance, these capacitors reduce capacitor-induced distortion to vanishingly low levels.
They are pricey but are a perfect addition to our products.
With MM/MC, high/low and very low, the ZEN Phono is able to handle just about any cartridge. From 36dB all the way up to 72dB. So as your vinyl system grows over time, the ZEN Phono will always keep up.
Balanced circuit design. Just not seen at this price point it is a superior method to the traditional single-ended circuit approach. Balanced circuits reduce noise and crosstalk. Less Interference – clearer sound.
