The Best Phono Preamps

Check two things before buying. First, does your turntable have a built-in preamp, usually with a switch labeled "phono/line" near the output jacks? Second, does your amp, receiver, or powered speaker set have a jack marked "phono" specifically, as opposed to "aux" or "line in"? A phono input already contains the RIAA equalization circuit; a line or aux input does not.

You need a standalone preamp only when both answers are no - a turntable with its preamp switched off (or without one at all) feeding an amp or speakers that only have line-level inputs. If either side already has a phono stage, adding a second one in the chain will make records sound distorted and too loud.

Almost every beginner turntable ships with a moving-magnet (MM) cartridge, which outputs a relatively strong signal and is what budget preamps like the Fluance PA10 and ART DJPRE II are built for. Moving-coil (MC) cartridges, common on higher-end turntables, output far less signal and need considerably more gain to reach the same volume.

Buying an MM-only preamp for an MC cartridge won't damage anything, but it will sound quiet and noisy. Going the other way - using an MC-capable preamp like the iFi Zen Air Phono 2, iFi Zen Phono 3, or Pro-Ject Phono Box S2 with an MM cartridge - works fine as long as the gain is switched down to the MM setting.

Gain is how much the preamp amplifies the cartridge's signal. Too little and you'll have to run your amp's volume much higher than usual, adding hiss; too much and quiet passages will sound fine but loud ones will distort. MM cartridges typically want somewhere in the 40 dB range; MC cartridges often need 60 dB or more, which is why fixed-gain budget preamps only support MM.

Loading - the resistance and capacitance the preamp presents to the cartridge - shapes frequency response at the margins. Cartridge makers publish a recommended loading value; preamps with switchable loading, like the iFi Zen Phono 3 and Pro-Ject Phono Box S2, let you match it instead of accepting a generic factory default. For a single MM cartridge on a budget setup, this rarely matters enough to justify the extra cost; for MC cartridges or anyone chasing a specific tonal balance, it does.

None of the picks above include a USB output. A handful of preamps on the market - Rega's Fono Mini A2D, for instance - add a USB port that sends the same equalized signal straight to a computer for digitizing records, on top of an otherwise ordinary MM circuit. It's a genuinely useful feature if you're archiving a collection, but it doesn't change how a preamp sounds through your regular speakers. If ripping vinyl to digital files is a real goal, shop for a USB-equipped preamp as its own category rather than expecting it bundled into a general-purpose pick like the ones above.

The Fluance PA10 and ART DJPRE II are the two cheapest ways to get a clean MM signal, with the DJPRE II adding a gain trim and switchable capacitance the PA10 lacks. The iFi Zen Air Phono 2 is the simplest way to cover both MM and MC in one box without paying for adjustable loading you may never touch. The Cambridge Audio Alva Solo costs about the same as the two step-up MC-capable options but stays MM-only, trading flexibility for a quieter standby circuit. The Pro-Ject Phono Box S2 and iFi Zen Phono 3 are the most adjustable boxes here: the S2 offers four gain and multiple loading combinations from an established turntable brand, while the Zen Phono 3 adds a wider gain range, independent loading control, and a balanced output for a more serious setup.
