If you’ve recently dusted off a classic turntable or picked up a budget deck to join the vinyl revival, you’ve likely hit a common snag: it sounds a bit quiet, or perhaps a bit flat. Enter the dedicated phono preamplifier. While many modern amplifiers and soundbars lack a dedicated phono input, the Pro-Ject Phono Box E promises to bridge that gap for Moving Magnet (MM) cartridges without breaking the bank. But in a market flooded with ultra-cheap £20 knock-offs and high-end audiophile gear, does this unassuming little black box actually deliver true hi-fi sound?
We synthesised official specifications, deep-dive user tests, and long-term customer reviews to find out if the Phono Box E is the budget hero your hi-fi setup needs.
The Quick Verdict 4.6 / 5 | The Pro-Ject Phono Box E is a brilliant, no-nonsense phono stage that dramatically outperforms its entry-level price tag. It is the perfect upgrade for vinyl newcomers and budget audiophiles looking to bypass cheap, built-in turntable preamps, though its minimalist “always-on” design won’t suit serial knob-twiddlers.
Pro-Ject Phono Box E, Hi-Fi Moving Magnet Phono Preamplifier (Black)
Phono Box E Overview
Designed with circuitry inspired by Dr. Sykora, the Pro-Ject Phono Box E is a highly compact, dedicated phono preamplifier exclusively for Moving Magnet (MM) cartridges. Its sole purpose is to take the minuscule audio signal generated by your turntable’s stylus and amplify it to a standard “Line Level” that any modern amplifier, powered speaker, or soundbar can understand, whilst applying the necessary RIAA equalisation curve. Pro-Ject promises audiophile-grade noise reduction through SMD circuitry and internal metal shielding, all housed in a discreet shell that can easily hide behind your turntable.
Core Feature Analysis
Design & Build Quality
- The Claim: A small, attractive chassis with internal metal shielding that allows for installation close to the record player without being intrusive.
- The Reality: Measuring just 120 x 32 x 100mm and weighing a mere 250g, it is incredibly diminutive. Synthesising user feedback, buyers consistently praise its minimalist aesthetic. There are no distracting, garish blue LEDs here, just a glossy black (or white) box that quietly gets on with the job. However, this minimalism comes at a cost: it has no power switch. It is designed to be permanently powered up.
- The Verdict: It delivers on subtlety. While the lack of an on/off switch might annoy some energy-conscious users, its tiny footprint means you can tuck it away out of sight and forget about it.
Audio Performance & RIAA Equalisation
- The Claim: Delivers a hi-fi music experience with special low-noise components that keep distortion at a surprisingly low level (THD <0.04%).
- The Reality: The consensus is overwhelmingly positive regarding audio fidelity. Users upgrading from £20 budget preamps (like older Behringer models) report a massive jump in clarity and power—often noting a distinct +10dB boost in apparent volume and a much wider soundstage. One long-term listener noted that swapping a cheap valve preamp for the Phono Box E was like “the difference between night and day,” citing punchy, controlled bass and a dead-quiet background.
- The Verdict: It comfortably punches above its weight. It brings warmth and detail to 75-year-old records and modern pressings alike, offering a genuine hi-fi experience for a fraction of the usual cost.
Setup & Usability
- The Claim: Simple to use, featuring gold-plated RCA connectors for the highest quality performance.
- The Reality: It’s essentially plug-and-play. You connect your turntable’s RCA cables to the input, attach the grounding wire to the dedicated GND terminal (crucial for stopping mains hum), and run the output to your amp. However, you must ensure your turntable’s built-in preamp is completely bypassed. Users plugging decks like the Audio-Technica LP60X into this box often report “muddy” sound. This isn’t the Pro-Ject’s fault; it’s a design flaw in cheaper turntables that fail to disconnect their internal capacitance even when switched to “Phono,” resulting in double-loading.
- The Verdict: Flawless usability, provided you pair it with the right equipment. It pairs beautifully with pure decks like the Rega RP1 or Pro-Ject’s own Essential line.
British Contextualisation
For the British audiophile, the price point hits a sweet spot. It’s often vastly superior to the built-in phono stages found on budget all-in-one systems sold in high street shops like Argos or Currys. Furthermore, older UK homes are notorious for poor mains earthing, which can introduce a nasty 50Hz hum into sensitive audio equipment. The Phono Box E’s outboard 18V DC power supply and internal metal shielding do a stellar job of rejecting this local interference, ensuring that the moody silences in your favourite Radiohead pressing remain genuinely silent.
Pro-Ject Phono Box E vs. The Competition
While the Phono Box E is a stellar performer, how does it stack up against true market rivals in the sub-£100 bracket?
| Feature | Pro-Ject Phono Box E | Art DJ Pre II | Rega Fono Mini A2D |
|---|---|---|---|
| Price (Approx) | £45.00 | £55.00 | £99.00 |
| Cartridge Support | MM Only | MM Only | MM Only |
| Gain Control | Fixed (40dB) | Variable | Fixed |
| USB Digitisation | No | No | Yes |
| Power Switch | No | Yes | No |
| User Rating | 4.6/5 | 4.7/5 | 4.8/5 |
The Winner by Use Case: Choose the Pro-Ject Phono Box E if you want a minimalist, set-and-forget analogue upgrade on a strict budget. Opt for the Art DJ Pre II if you have a variety of cartridges and need adjustable gain controls (though you’ll have to put up with its rather ugly, flashing aesthetic). Stretch your budget to the Rega Fono Mini A2D only if you specifically need USB functionality to digitise your vinyl collection to a Mac or PC.
Our Verdict
The Pro-Ject Phono Box E is a masterclass in budget audio engineering. It strips away every unnecessary bell and whistle—including the power switch—to invest every penny of its £45 asking price into internal shielding, low-noise SMD circuitry, and gold-plated connections. For the burgeoning vinyl enthusiast looking to breathe life into a vintage deck, or someone seeking an immediate, noticeable upgrade over a cheap built-in turntable preamp, it is an absolute no-brainer. Just ensure your deck allows for a true bypass of its internal stage to get the sparkling highs and punchy lows this brilliant little box is capable of delivering.
