On this page you’ll find a ranking of the best Phono preamps from Pro-Ject. To give you a quick overview, we’ve added the most important product details. This page always stays fresh and updates automatically.
1. Pro-Ject Phono Box
Many currently available HiFi devices and music systems do not have a connection for turntables. The Phono Box is the ideal solution here, as this phono preamp is suitable for both MM and MC cartridges. The analog output of the Phono Box is simply connected to a line input (AUX, ...) of your amplifier.
2. Pro-Ject Optical Box E Phono
Those who want to use their record player together with home cinema receivers, soundbars or all-in-one systems sometimes only find digital inputs and will therefore love this little box. The Optical Box E Phono takes this need into account and offers a digital-optical signal output as well as an analogue one, whereby both can be used simultaneously. Therefore it can also be used as a signal splitter 1>2 and can be used as an uncomplicated input signal extension 2>1, where no free input is available.
Last but not least, the Optical Box E Phono is capable of digitizing not only phono signals, but also high-level signals from cassette decks or radio. In order to preserve these as unaltered as possible, the A/D conversion is performed with the highest precision at 24bit / 96kHz resolution. It can also be integrated into any hi-fi system as a normal MM phono preamplifier with line output (3.5mm jack).
The inside of the cabinet is lined with metal, eliminating RF interference and vibration for an undisturbed listening experience. The Optical Box E Phono is the perfect partner for all modern audiophiles who want to enjoy their analog signal sources with digital or analog playback devices!
3. Pro-Ject Pre Box S2 Digital Edition 2023
The Pre Box S2 Digital Edition 23 takes Pro-Ject's preamplifiers into a new era thanks to the dual-mono design with the highest quality ESS Sabre D/A converters. This allows you to enjoy first-class quality that can resolve up to 32-bit/768 kHz in PCM encoding. The Pre Box S2 Digital Edition 23 has an improved power management design compared to the previous model. With up to seven digital filters, you can customise the sound to your liking and ensure you get the soundscape that suits you every time. The device also works with a remote control and can be used to control the playback programmes on your computer. You can change tracks or pause them directly from the Pre Box.
4. Pro-Ject Tube Box S2
The Tube Box S2 is our first product that features a fully discrete design and operates without any operational amplifiers (OpAmps). It is also the first product that allows users to swap the installed tubes, enabling them to shape the sound according to their personal preferences with different tubes. The Tube Box S2 delivers an exceptionally relaxing sound with rich mids, typically found only in much more expensive tube preamps. Both MM systems and MC cartridges can be connected, with a variety of gain stages selectable from the front. Five variable input impedances are available to adapt to any system; the 47 kOhm setting is fixed and suitable for high output MC cartridges. The aluminum/metal housing is visually aligned with that of the DS2 series and effectively protects against vibrations and electromagnetic interference, ensuring a clear sound. A true high-end solution in a much smaller format.
5. Pro-Ject Phono Box DS2
Premium Phono Preamplifier for MM & MC Cartridges
The Phono Box DS2 is an extremely customizable phono preamp that is well-suited for both MM and MC systems. With the ability to switch between input impedance and capacitance as well as gain from the front panel, it becomes one of the most user-friendly phono stages in its price range. It features a pair of RCA inputs for a turntable and a pair of RCA outputs to connect to a preamplifier or integrated amplifier. The housing is a durable aluminum/metal sandwich construction that not only effectively protects against electromagnetic interference and vibrations but also provides an aesthetic appeal that is pleasing to the eye. The design of the Phono Box DS2 is kept very linear, resulting in the best possible sound from a minimalist PCB. With its high sound quality combined with a low price, the Phono Box DS2 is a true audiophile bargain!.
6. Pro-Ject Phono Box S2
The Phono Box S was one of the favorite products, offering undisputed great sound and versatility at a very moderate and affordable price. When Pro-Ject began planning the Phono Box S2, it naturally had to have the same superior features as the Phono Box S, but with even further improved sound quality. The Phono Box S2 delivers incredible detail resolution, dynamics, and precision, combined with a soundstage typically found only in much more expensive products. The switches on the bottom of the device provide a variety of options to shape the sound to your liking and allow the Phono Box S2 to be adapted to any cartridge system. The new S2 housing is made from an aluminum/metal sandwich construction, offering not only a unique aesthetic but also effectively protecting against vibrations and unwanted interference. The Phono Box S has been the best solution in the entry-level phono preamp market, and the Phono Box S2 follows in the footsteps of its successful predecessor, setting new standards at this price point.
7. Pro-Ject Record Box E
The Record Box E is a high-quality phono preamplifier that offers the ability to convert vinyl into digital music files. It allows for the connection of both MM and MC cartridges and provides audiophile sound enjoyment at an entry-level price. The integrated A/D converter is compatible with Windows and Mac operating systems and can be connected to a computer via USB. This enables your valuable vinyl collection to be used in digital form with portable music players. A modern circuit design based on SMD technology minimizes noise and distortion. The built-in shielding and external power supply significantly reduce the chance of external interference. Due to its compact size, the Record Box E can be placed close to the turntable. Both the RCA input and output jacks are gold-plated to prevent corrosion. The Record Box E connects to the amplifier's line input.
8. Pro-Ject Pre Box S2 Digital
The Pre Box S2 Digital marks a new era for the S-Series components. For the first time ever, we use a double-mono construction with top-class D/A converters from ESS Sabre. This DAC is capable of converting high resolution files up to 32bit/768kHz PCM and DSD512. Pre Box S2 Digital is also the first of the products to support MQA hardware decoding. It also marks the premiere of the proprietary Optimum Transient Filter and proprietary clock circuitry. Digital audio is the art of the age, with proprietary clock design, the S2 Digital has been able to achieve jitter values of 100 femtoseconds, values that dwarf many highly regarded and respected clock generators. With organic propylene capacitors and thin film miniMELF resistors, this little wonder could build a clock that can declass much larger and more expensive hardware. With seven digital filters the customer can shape the sound according to his wishes. The Pre Box S2 Digital is fully remote controllable and can even control the computer's playback software.
9. Pro-Ject Phono Box S2 Ultra
The Phono Box S is extremely flexible. Every cartridge performs best in an optimal electrical environment. The phono preamplifier can be finely adjusted to the requirements of the cartridge in terms of termination capacitance, termination resistance, and gain. Unusually for this price range, the device offers a variety of adjustment options for the termination capacitance of MM, Moving Iron, and High-Output MC cartridges, as well as for the termination resistance of Low-Output MC cartridges. The gain can be set in four stages and is not tied to a specific operating mode. All settings can be used for both MM and MC modes.
