Schiit Mani 2 Review

What problem this solves

A cheap phono stage makes one assumption on your behalf: that you have a moving-magnet cartridge putting out somewhere around 4–5 mV, and that loading it at 47 kΩ is fine. For a large majority of turntables that assumption is correct and the cheap box is the right purchase.

It stops being correct the moment you do anything interesting with cartridges. A low-output moving coil produces a fraction of that voltage and needs both far more gain and a much lower load impedance. A moving-iron design sits somewhere else again. Change cartridge families with a fixed-gain preamp and you are buying a new preamp too.

The Mani 2 exists to remove that ceiling for a price that is still well inside what most people spend on a cartridge. Schiit specifies four gain settings (35, 45, 50 and 60 dB), four resistive loads (47 kΩ, 200 Ω, 47 Ω and 38 Ω) and four capacitance values (47, 100, 150 and 200 pF). That is sixty-four combinations, and it means the box outlives every cartridge decision you are likely to make.

Gain: what the four settings are for

Gain is the amount of amplification applied to the cartridge’s output. Too little and the signal never reaches usable level, so you run the volume control at maximum and hear the noise floor. Too much and loud passages clip.

Roughly how the four settings map onto real cartridges:

• 35 dB— high-output moving-magnet cartridges, and the setting to try first if a normal MM sounds hot or distorted at the next step up.
• 45 dB— the standard moving-magnet setting. An Ortofon 2M Red at 5.5 mV or an Audio-Technica VM95E sits here.
• 50 dB— high-output moving coils and moving-iron designs, which fall between the two families.
• 60 dB— low-output moving coils, the cartridges producing a few tenths of a millivolt.

Set it from your cartridge’s published output figure rather than by trial and error where possible — gain and impedance explained works through the arithmetic, and MM vs MC explains why the two families differ so much in the first place.

Loading: the setting nobody explains

Loading is the electrical impedance the preamp presents back to the cartridge. The cartridge is a coil and a magnet; what it sees at its output affects how it behaves, particularly at the top of its range.

For moving-magnetcartridges, the resistive value is settled — 47 kΩ, and every MM cartridge is specified for it. What varies is capacitance, which includes the capacitance of your tonearm cable, and it shifts the high-frequency response audibly. Manufacturers publish a recommended range; being able to choose 47, 100, 150 or 200 pF lets you land inside it instead of hoping.

For moving-coilcartridges the resistive load is the important one and the values are far lower — the 200, 47 and 38 Ω settings exist for exactly this. A common rule of thumb is to load a moving coil at several times its internal impedance; the cartridge maker usually publishes a recommendation, and the Mani 2 gives you enough steps to follow it.

None of this is audible as a dramatic difference. It is audible as the top end being slightly bright or slightly dull, and being able to correct it is one of the small pleasures of owning an adjustable stage.

The subsonic filter, which is more useful than it sounds

Schiit specifies purely passive low-frequency filtering at 15 Hz, switchable between 6 dB and 12 dB per octave. Two details matter there.

Why you want one.A warped record makes the tonearm rise and fall once per revolution, which at 33 1/3 RPM is about 0.55 Hz. Turntable rumble adds more energy in the same region. None of it is audible as music, but all of it is amplified along with the music, wasting amplifier headroom and making woofers visibly flap. Removing it can make a system sound cleaner in the midrange purely by giving the amplifier less pointless work.

Why “passive” matters.A passive filter uses no active components in the signal path — it is resistors and capacitors doing the work rather than another amplification stage. That is the less intrusive way to do it, and it is unusual at this price.

Two slopes gives you a choice: 6 dB/octave is gentle and safe on everything; 12 dB/octave removes more of the problem and is the one to use with badly warped records. If your records are flat and your deck is quiet, leave the filter out. If you buy secondhand, you will use it.

What it does not have

No tubes, no display, no remote, no balanced outputs, and no volume control — it is a phono stage, not a preamplifier in the wider sense, so it feeds a line input on something else. It also has no mono switch, which is a genuine omission if you collect mono pressings.

And, as Schiit states clearly, this version is 115 VAC only, suitable for the US, Canada and Mexico, and will not work on 220–240 V mains. That is a specification, not a flaw, but it is the kind of thing worth reading before ordering internationally.

Where it sits in a system

Between the turntable and a line input on whatever comes next. The turntable’s own preamp, if it has one, must be switched to PHONO so that the Mani 2 is the only phono stage in the chain — the double-preamp mistake is covered in phono vs line.

It pairs naturally with the decks that deliberately omit a preamp: the Fluance RT85, the RT82, the U-Turn Orbit and the Pro-Ject Debut range. On a deck like that, with a good cartridge fitted, the adjustable loading actually earns its keep.

Who should buy it

Buy the Mani 2 if you expect to own more than one cartridge over the life of the deck; if you have or want a moving-coil cartridge; if you buy secondhand records and want the subsonic filter; or if you simply want to stop thinking about the phono stage.

Buy the Fluance PA10 or another fixed-gain moving-magnet stage instead if you own one MM cartridge, are happy with it, and would rather put the difference into the cartridge itself. That is a defensible allocation, and phono preamps under $100 covers the field. The whole range, including the tube options, is in tube vs solid state.
