With the Zen Phono 3, Ifi Audio brings us the latest iteration of their renowned range of phono preamplifiers. The Zen Phono 3 is a versatile, ultra-quiet phono preamplifier with multiple gain and impedance settings to suit all cartridges, whether moving-magnet (MM) or moving-coil (MC).
The design of the Zen Phono 3 has been designed with the reduction of any potential parasitic noise in mind. Indeed, the Zen Phono 3 integrates an ultra-quiet power supply isolated away from other components on the PCB, thus greatly reducing the background noise its proximity could generate. Furthermore, the power supply features Active Noise Cancellation II technology, which cancels all incoming EMI and RFI noise. As a result, the Zen Phono 3 boasts an IEN (Equivalent Input Noise) of -151 dBV.
As for the signal processing itself, amplification is handled by a low-distortion (0.0001%) custom OPA from the OV series. The Zen Phono 3's RIAA equalization circuit uses several TDK C0G capacitors in parallel, for greater stability and minimum distortion. This enables the RIAA equalization curve to have a tolerance of +/- 0.15 dB between 20Hz and 20 kHz, allowing you to listen to your records with greater precision than ever before.
To adapt to any type of cartridge, the Zen Phono 3 supports four MM/MC gain selections from 36 to 72dB and four input impedance settings. For gain adjustment, there's a selector on the rear of the unit, while impedance adjustment is via the front-panel knob. So you can experiment and find the perfect setting to suit your ears.
Conventional subsonic filters are generally poorly appreciated by audiophiles because of the bass deterioration they cause. Since 2012, however, Ifi Audio has been developing its own subsonic filter, which uses artificial intelligence to distinguish the bass of the track from the parasitic hum that accompanies it. In this way, the original signal is left completely intact with no group delay.
