The Best Phono Preamps: 4 Compared (and One to Skip)

RBE top pick

Schiit Mani 2

The Mani 2 gives you moving magnet, moving iron and moving coil support with four gain settings and, unusually, adjustable load capacitance, at a price where rivals hand you one fixed option. Step up to the ZEN Phono 3 only if a low-output moving coil cartridge is in your present or your plans, because that is where its much higher gain ceiling earns the difference.

See why it wins Compare all

A phono preamp boosts a cartridge's tiny output and reverses the RIAA curve cut into the record. Before you shop, check the back of your turntable for a PHONO/LINE switch and your amplifier for a PHONO input, because most people already own one and the second box adds nothing. If you genuinely need an external stage, the real separators are cartridge type support, how much gain you can get, and whether you can set the loading your cartridge asks for. Two of these four are easy recommendations, one is a narrow specialist, and one is the purchase this category is famous for wasting money on.

RBE top pick

Schiit Audio

Schiit Mani 2

Buy it

Four gain settings, four resistive loads and four capacitance settings, at a price where rivals give you a single fixed option.

Best for: Almost anyone stepping up from a built-in phono stage, and especially moving magnet owners who want to dial in load capacitance properly.

$$ · mid-range

Why we like it

• Handles moving magnet, moving iron and moving coil, with gain spanning roughly 35dB to 60dB
• Adjustable load capacitance for MM cartridges, a genuinely rare feature at this price and one that changes treble balance audibly
• Four resistive loading options down to the low values low-output moving coil cartridges want
• Two-slope low-frequency filter for warped records and turntable rumble
• Independent testing reports a low noise floor and accurate RIAA equalization; passive equalization with no capacitors in the main signal path

Know before buying

• Settings are on rear switches rather than front-panel controls, so changing loading means reaching behind the unit
• Unbalanced RCA output only
• Top gain setting is generous but not limitless, so the very quietest exotic moving coil cartridges will push it

iFi Audio

iFi ZEN Phono 3

Buy it

The one to buy if moving coil is in your plans, thanks to a much higher gain ceiling and independently selectable loading.

Best for: Owners of low-output moving coil cartridges, and anyone building toward one who does not want to buy a phono stage twice.

$$ · mid-range

Why we like it

• Four gain settings from roughly 36dB up to 72dB, enough headroom for genuinely low-output moving coil cartridges
• Gain and loading are chosen independently rather than locked into fixed MM and MC modes
• MC loading at 100, 400 and 1000 ohms covers most published cartridge recommendations; MM gets 47k ohms with a capacitance choice
• Subsonic filter targets warp-rate energy rather than blanket-rolling the bass, and adds no group delay
• Published noise specification is excellent, and owner reports back it up on quiet grooves

Know before buying

• Costs meaningfully more than the Mani 2 for an advantage that only shows up at the moving coil end
• Balanced output uses a connector many integrated amplifiers do not have
• Curved chassis does not stack with rectangular components and divides opinion

Rega

Rega Fono MM Mk5

It depends

A superb moving magnet stage that does one thing perfectly and refuses to do anything else, for more money than the rivals that do both.

Best for: A settled moving magnet system whose owner has no intention of ever going moving coil and wants sound quality over switches.

$$$ · premium

Why we like it

• Fully discrete cascaded input stage with the RIAA equalization split across two stages to stop the sections interacting
• Reviewers consistently report very low noise, clean transients and a lively sense of timing
• Roughly 41dB of gain, which is exactly right for a normal moving magnet cartridge
• Rigid low-resonance machined aluminum case, with repeated recognition in independent award roundups at its level

Know before buying

• Moving magnet only, with no MC mode at all
• Fixed loading: no resistive switch, no capacitance switch, so your cartridge has to be happy with Rega's chosen values
• No rumble or subsonic filter, which is a real omission at this price if your records are less than flat
• Costs more than both picks above while doing strictly less

We'd skip it

Behringer

Behringer Microphono PP400

Skip it

Competent for the money, but almost everyone who buys it already has a phono stage built into gear they own.

Best for: The narrow case of a vintage or bare turntable plus an amplifier with no phono input and a hard budget ceiling.

$ · budget

Why we like it

• Genuinely cheap, and it does work if you have a bare turntable and an amplifier with no phono input
• Tiny footprint with RCA in and out plus a quarter-inch output
• Ground terminal included, which cheap competitors sometimes omit
• Independent listening comparisons have found it competent rather than broken

Know before buying

• Moving magnet only, roughly 35dB of gain into a fixed load, with no MC support at all
• No loading adjustment, no capacitance adjustment and no rumble filter
• Published signal-to-noise figure is modest next to everything else here
• Redundant for most buyers, since their turntable or receiver already contains a phono stage that this does not beat

How we judged the field

A phono preamp does two jobs and nothing else. It boosts a cartridge signal that arrives thousands of times quieter than a line-level source, and it reverses the RIAA equalization curve that was baked into the record when it was cut. Everything else (chassis, knobs, tube glow) is packaging around those two jobs.

Because we do not run a lab, we work the way a careful shopper would if they had unlimited time: we read published independent bench testing for noise floor, RIAA curve accuracy, gain accuracy and overload headroom, then we cross-check that against a large volume of owner reports covering hum, hiss, rumble on warped records and cartridge matching problems that only show up after months of use. Where measurements and owners disagree, we say so.

The criteria that actually separated these four:

Cartridge support. Moving magnet (MM) cartridges output roughly 3 to 6 millivolts and want about 47k ohms of resistive loading, plus a capacitance figure the cartridge maker specifies. Moving coil (MC) cartridges output a tenth of that or less and want a much lower resistive load, often between 100 and 1000 ohms. A stage that only does MM is not defective, it is just narrower. A stage that claims MC but offers one fixed load is doing MC badly.

Gain range and steps. An MM cartridge needs roughly 40dB of gain. A high-output MC needs a bit more. A genuinely low-output MC, the kind that puts out a few tenths of a millivolt, needs 60dB or more before your amplifier volume control stops running out of travel. Gain that stops too low is the single most common mismatch we saw in owner reports.

Loading flexibility. Resistive loading changes MC treble balance audibly. Capacitive loading changes MM treble balance audibly. Cartridge manufacturers publish recommended values. A preamp that lets you hit them is worth more than one that sounds slightly prettier on a fixed setting.

Noise floor and rumble handling. Vinyl carries subsonic energy from warps and from turntable rumble. Without a subsonic or rumble filter, that energy eats amplifier headroom and can make woofers visibly flap. This is a feature that costs a manufacturer almost nothing and that owners notice immediately when it is missing.

Whether you need the box at all. This is the criterion nobody puts in a spec sheet, and it is the one that decides most purchases in this category. Most turntables sold in the last decade have a built-in phono stage with a PHONO/LINE switch on the back. Most receivers and integrated amplifiers with an input labeled PHONO have one too. Powered speakers aimed at vinyl buyers frequently have one. Buying an external stage that is no better than the one already in your system is the most common wasted purchase here, and no amount of enthusiasm about component quality changes that.

Schiit Mani 2 - buy

The Mani 2 is the rare product where the feature list reads like a much more expensive item and the performance does not fall over when you check. It handles moving magnet, moving iron and moving coil cartridges, with four gain positions spanning roughly 35dB to 60dB. That top setting is the important one: it is where low-output moving coil cartridges become usable without you pinning the volume control.

Loading is where it separates from cheaper competition. You get four resistive settings, from the standard 47k ohms for MM down through 200, 47 and 38 ohms for various moving coil designs, and four capacitance settings from 47pF up to 200pF for MM. That last part matters more than most buyers realize. MM cartridges specify a total load capacitance including your tonearm cable, and getting close to the specified figure is the difference between a natural top end and a peaky, glassy one. Very few affordable stages let you change it at all.

There is also a genuine low-frequency filter with two slopes, one gentle and one steeper. Independent testing consistently reports a low noise floor and an accurate RIAA curve, and the circuit uses passive equalization with no capacitors in the main signal path. Owner reports skew heavily toward “quieter than the phono input in my receiver,” which is the entire reason to buy an external stage in the first place.

Where it gives ground: the settings live on switches rather than front-panel controls, so changing loading means reaching around the back and, on some units, working with small switches you cannot read in dim light. Output is unbalanced RCA only. And the top gain setting, while generous, is not unlimited, so the very quietest exotic moving coil cartridges will still push it. For the overwhelming majority of buyers stepping up from a built-in stage, none of that will ever come up.

iFi ZEN Phono 3 - buy

The ZEN Phono 3 is the one to pick if moving coil is your present or your near future. Its four gain settings run from roughly 36dB to 72dB, and that upper figure is meaningfully higher than what most affordable stages offer. If you own or plan to own a low-output MC cartridge, this is the practical difference between a system that plays at a normal volume setting and one that does not.

The loading arrangement is unusually sensible. Gain and loading are chosen independently rather than being welded together into fixed MM and MC modes, so you can run a high-output moving coil at MM-ish gain while still loading it correctly. MM gets 47k ohms with a choice of capacitance, and MC gets 100, 400 or 1000 ohms, which covers the great majority of published manufacturer recommendations.

The subsonic filter deserves a specific mention because it is implemented better than the usual approach. Rather than a blanket low-frequency rolloff that thins out real bass, it targets warp-rate energy while leaving musical bass alone and without introducing group delay. Owners with warped records or a springy floor consistently report this as the feature they did not know they needed. Published noise specifications are excellent, and listener reports back that up: with a moving coil cartridge and a quiet groove, you should be hearing the record, not the electronics.

It also offers a balanced output alongside RCA, which is useful if your amplifier accepts it and irrelevant if it does not. The reservations are aesthetic and practical rather than sonic. The curved chassis is divisive and does not stack neatly with rectangular gear, the balanced output uses a connector that many integrated amplifiers simply do not have, and it costs meaningfully more than the Mani 2 for an advantage that only materializes at the moving coil end. If you own an MM cartridge and intend to keep owning one, you are paying for range you will not use.

Rega Fono MM Mk5 - it depends

This one is easy to describe and hard to place. It is a moving magnet stage, full stop. There is no MC mode, no loading switch, no capacitance switch, no rumble filter. Rega picked one set of values, built a fully discrete cascaded input stage around them, split the RIAA equalization into two stages to keep the sections from interacting, and put it in a rigid low-resonance aluminum case. Gain sits at roughly 41dB, which is exactly right for a normal MM cartridge and useless for anything quieter.

Reviewers describe it in consistent terms: very low noise, clean transient attack, and a sense of timing and drive that makes the presentation feel alive rather than merely accurate. It has collected repeated recognition in independent award roundups at its price level, which is not the same as a measurement but does say something about how it holds up against fresh competition year after year.

So why is it a “depends” rather than a “buy”? Because it costs more than the two picks above while doing strictly less. If you own a good MM cartridge, have no intention of ever going moving coil, and your cartridge is happy at Rega’s fixed loading, this is a genuinely lovely piece of electronics and the lack of switches is a feature rather than a limitation. If any of those conditions might change, you are paying a premium for a box you will outgrow. The missing rumble filter is also a real omission at this price if your records are less than perfectly flat.

Buy it as a considered destination for an MM system. Do not buy it as a first external phono stage while you are still working out what cartridge you want.

Behringer Microphono PP400 - skip

The PP400 is the box that appears in the “customers also bought” slot next to every turntable, and it is the reason this category has a reputation for wasted money. It is a moving magnet stage offering roughly 35dB of gain into a fixed load, with RCA in and out plus a quarter-inch output, powered by a small external adapter. There is no MC support, no loading choice, no capacitance choice and no rumble filter. Its published signal-to-noise figure is modest by the standards of the rest of this group.

To be fair to it: it is not junk. Independent listening comparisons have found it competent for the money, and if you genuinely have a bare turntable with no built-in stage and an amplifier with no phono input, it will get music playing. That is a real use case.

The problem is that it is almost never the use case of the person buying it. Check the back of your turntable for a PHONO/LINE switch, and check your amplifier or receiver for an input labeled PHONO. If either exists, you already have a phono stage, and this one is not an upgrade over it. Adding it will not improve anything and, if you accidentally run it into a phono input that is already active, you will get a distorted, wildly over-equalized mess.

There is a second trap here. The performance ceiling of a vinyl front end is set overwhelmingly by the cartridge, the stylus condition and the tonearm setup, not by the last inch of the electronics. Money spent on this box is money not spent on the stylus that is actually touching the record. If your current sound disappoints you and you already have a working phono stage, replace the cartridge before you replace the preamp.

Schiit Mani 2 vs iFi ZEN Phono 3: which should you buy?

These two solve the same problem from opposite ends, and the deciding factor is your cartridge, present and future.

The Mani 2 wins on capacitance. It is one of very few stages at any accessible price that lets you set MM load capacitance across a useful range. If you run moving magnet cartridges and care about getting the treble balance right, that single feature is worth more than everything else on either spec sheet. It also costs less, it is compact, and its noise floor is low enough that most owners describe the upgrade from a built-in stage as immediately obvious.

The ZEN Phono 3 wins on moving coil. Its top gain setting is substantially higher, its resistive loading options for MC are better spread across what cartridge makers actually recommend, and it lets you set gain and loading independently rather than forcing you into a preset MM or MC mode. Its subsonic filter is the smarter design of the two, targeting warp energy rather than blanket-rolling the bass. It also gives you a balanced output if your amplifier has the matching input.

Practical decision rule. If you own a moving magnet cartridge and expect to stay there, take the Mani 2 and put the difference toward a better stylus. If you own a low-output moving coil cartridge, or you are building toward one, take the ZEN Phono 3, because the Mani 2’s gain ceiling will eventually become the thing you are working around. If you are somewhere in between with a high-output moving coil, either works, and the Mani 2’s price advantage makes it the sensible default.

What to look for

• First, check whether you already have one. Look for a PHONO/LINE or PHONO/AUX switch on the back of your turntable. Look for an input marked PHONO on your amplifier or receiver. If you find either, you have a phono stage, and an external one is an upgrade to evaluate, not a missing part to buy.
• Never run two in series. Turntable built-in stage into an amplifier phono input gives you double equalization and double gain: loud, thin and distorted. Switch one of them off, or use a line-level input.
• Match the cartridge type before anything else. MM cartridges need around 40dB of gain and 47k ohms. Low-output MC cartridges need 60dB or more and a load usually between 100 and 1000 ohms. A stage that cannot reach your cartridge’s requirements will never sound right no matter how good its components are.
• Treat capacitance as a real specification, not a footnote. Your MM cartridge maker publishes a recommended total load capacitance, and your tonearm cable already contributes some of it. Adjustable capacitance lets you land near the target instead of hoping.
• Want a rumble or subsonic filter. Warped records and turntable rumble put energy below the audible band into your amplifier. A filter costs the manufacturer almost nothing and saves headroom. Its absence is a genuine mark against a stage at any price above budget.
• Check the output type against your amplifier. A balanced output is only an advantage if you have a balanced input to plug it into. Otherwise it is a spec you paid for and cannot use.
• Look at the power supply and placement. Most of these run from an external adapter. Keep that adapter and the preamp away from the turntable’s motor and from mains cables, because induced hum is the most common complaint in owner reports and it is usually a placement problem rather than a product fault.
• Spend on the cartridge first. In a modest system, a better stylus changes more than a better phono stage. Preamp upgrades pay off once the cartridge and setup are already good.

Our final take

The most useful thing we can tell you about this category is that a large share of the people shopping in it do not need to be. Turntables and receivers have shipped with competent built-in phono stages for years, and the correct first move is to go look at the back panel of the gear you already own.

If you look and find you genuinely need a stage, or you have listened to your built-in one and want better, the Schiit Mani 2 is the pick. It offers gain and loading flexibility that competitors twice its price do not, including the adjustable capacitance that moving magnet cartridges actually respond to, and independent testing and owner reports agree on its low noise floor.

Choose the iFi ZEN Phono 3 instead if moving coil is in your plans. Its higher gain ceiling, better spread of MC loading options and smarter subsonic filter are exactly what a low-output cartridge needs, and none of that is available on the Mani 2 at the same level.

The Rega Fono MM Mk5 is a specialist. It does moving magnet beautifully and does nothing else, so buy it as a destination for a settled MM system rather than as a starting point.

The Behringer Microphono PP400 is the skip. Not because it is bad at what it does, but because what it does is almost certainly already happening inside a component you own. If your vinyl sounds disappointing and you already have a working phono stage, the stylus is where your money belongs.
