The ZEN Phono — Four Gain Settings and a Balanced Output, at $199

A balanced output on a two-hundred-dollar phono stage is unusual enough to be the headline. The ZEN Phono carries a 4.4 mm balanced socket wired to the Sony standard, alongside the conventional RCA pair, and uses balanced circuitry throughout to get there.

The other half of the story is range. Four gain settings cover 36, 48, 60 and 72 decibels, which takes the ZEN Phono from an ordinary moving magnet cartridge all the way to a very low-output moving coil without any part of that span being a compromise.

What iFi Built Into It

The Four Gain Positions

Moving magnet sits at 36 dB. Moving coil runs 48 dB for high output, 60 dB for low and 72 dB for very low, each within a decibel. A rear switch selects the position and one of four LEDs on the front panel confirms which one is currently live.

How Quiet It Stays

Signal-to-noise measures 94 dB A-weighted in moving magnet mode and 90 dB at the 60 dB moving coil setting. Harmonic distortion on moving magnet comes in below 0.0003 percent. Reaching 72 dB of gain while holding a noise floor there is the hard part of this design, and it is where the money went.

The Subsonic Filter, and Why It Is Different

Most subsonic filters take real bass and phase accuracy away along with the rumble. iFi's removes only the vertical low-frequency content a warp produces, with a −3 dB point at 16 Hz. The lowest notes actually cut into records generally start around 32 Hz.

Balanced Output, and What It Is For

If your amplifier has balanced inputs, the 4.4 mm output keeps the signal differential the whole way and rejects the interference a single-ended cable picks up. Running the RCA pair instead costs you that, but works with everything.

Who Is the iFi ZEN Phono Best For?

• Owners of a low-output moving coil cartridge on a real budget — 72 dB at this price is genuinely rare, and it arrives with a noise floor that can carry it.
• Anyone with balanced inputs downstream, who can use the 4.4 mm output and keep the phono signal differential right through to the amplifier.
• Listeners expecting to change cartridges. Four gain positions mean the stage follows you from a moving magnet through to a 0.2 mV moving coil without another purchase.
• People with warped records, who get a filter that removes the warp and leaves the bass and the phase response where they were.
• Not for anyone who wants to set gain and loading independently — on this model the load follows the gain switch. The iFi ZEN Phono 3 separates the two, with four gain settings and four impedance settings chosen freely.

How Does It Connect?

RCA in from the turntable, ground wire to the post, then either the RCA pair or the 4.4 mm balanced socket to your amplifier. Power is 5 volts DC at 500 mA, which a USB port with a suitable cable will supply if you prefer.

Set the gain switch on the rear before you power the unit up, not after, and check the front LED matches your cartridge type. The subsonic filter is a button you can leave off until a record shows you it is needed.

Pairs Well With

The ZEN Phono was designed as part of a system, not as a single box:

• A low-output moving coil cartridge — the 60 and 72 dB settings exist for precisely these, and most stages at this price cannot run them.
• A headphone amplifier — the ZEN Phono has no headphone output of its own, and its balanced socket pairs naturally with one that does.
• A shielded tonearm cable — balanced circuitry inside the box cannot undo interference the cable picked up before it arrived.
• Cleaning fluid and a brush — at 94 dB the background is quiet enough that surface noise becomes the limiting factor.

Frequently Asked Questions

Which gain setting should I use?

Match it to your cartridge's output. Moving magnet takes 36 dB, high-output moving coil 48 dB, and low or very low output designs need 60 or 72 dB. iFi's advice is to pick the lowest setting that still gives comfortable listening levels.

How is the balanced output wired?

To the Sony standard, on a 4.4 mm connector. If your amplifier has balanced inputs this is the connection worth making; if it does not, the RCA pair alongside it gives you everything except the interference rejection.

Can I power it from a USB port?

Provided the port supplies 5 volts and you have a suitable cable, yes. The DC input is center-pin positive and tolerates 5 volts plus or minus ten percent, so a range of supplies will run it without complaint.

Should I leave the subsonic filter engaged?

Engage it when you can see your woofers moving on a record that is not flat. Because the filter only removes vertical low-frequency content below its 16 Hz corner, leaving it on costs you very little on records that do not need it.

Can it stay powered all the time?

It can. iFi's own guidance is to switch it off when you do not plan to use it for a while, purely on energy grounds — there is nothing about the design that requires it to be left running or to warm up for long.

How big is it?

Roughly 6.2 inches wide, 4.6 deep and 1.4 tall, weighing 515 grams. That is larger than the smallest phono stages here, and the extra volume is where the four gain stages and the balanced circuitry live.
