Turn On Tranquility - #iFi Audio #ZENPhono3 Preamplifier #unboxed

In a world where modern technology is ever-evolving, simplicity and connection are what we crave most. Nothing demonstrates this quite like the familiar act of picking your favourite LP, hearing the soft crackle before it starts, and sharing a story or two with friends as you listen together. If this is the type of connection you crave, then a well-designed phono stage is integral for your vinyl setup. It takes the subtle whispers of your cartridge and amplifies them hundreds of times, making your vinyl’s magic compatible with headphones, amps, receivers and speakers.

The ZEN Phono 3 opens the door to that analogue world with style and substance. With an intelligent warp filter and versatile loading options, you will be able to hear your over-loved LPs as new and fully experiment with your system setup.Packed with trickle-down technology from our prestigious history with sister company AMR, the ZEN Phono 3 is a noise-free upgrade that will allow you to slip seamlessly back into the blissful world of vinyl.

Features…
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
Super Smart, Super Subsonic

Standard subsonic filters aren’t intelligent and are typically loathed by audiophiles. They filter not only the bass rumble from warped records but also the bass of the song. The intelligent subsonic filter from ifi knows the difference between the two and only filters the warp, leaving the song completely intact, and without adding group delay.

Your Cartridge, Your Rules

The ZEN Phono 3 supports four MM/MC gain selections from 36 to 72dB and four input impedance settings. Mix and match gain and loading settings independently of each other with the all-new loading button, ensuring optimum compatibility with a wide range of cartridges and allowing you to get the sound ‘just right’.

Exacting Equalisation

At the vinyl mastering stage, records are pressed with an inverse RIAA equalisation curve applied. This needs to be undone on playback by the phono stage to reveal the magic of the music. ZEN Phono 3’s RIAA EQ circuitry uses multiple TDK C0G capacitors in parallel. This is for best stability and the least distortion. This allows for ZEN Phono 3’s RIAA playback equalisation curve to be within +/- 0.15dB tolerance from 20-20kHz, allowing you to hear your records more accurately than ever before. Its RIAA accuracy is on-par with more costly phono stages that use hand-selected capacitors.

Shockingly Silent

ZEN Phono 3 has a high-tech clean power supply built directly into it, isolated on its own “island” and away from the rest of the board. The power supply’s isolation mitigates noise pollution of the analogue stage – ensuring that only the audio is amplified and allowing for the noise-floor to remain whisper quiet.

ZEN Phono 3’s Equivalent Input Noise measures at -151dBV, which is 20dBV quieter than some Stereophile Class A+ phonos.

For optimal noise performance, you can also add the iFi audio iPower2 for an ultra-quiet, ultra-clean audiophile-grade power supply (featuring Active Noise Cancellation II technology).
