Thorens MM-002 MM Phono Preamplifier at Vinyl Sound Buffalo, NY USA

The Thorens MM-002 is a compact, high-quality moving magnet phono preamplifier from Thorens (Lahr, Germany), available at Vinyl Sound in Buffalo, NY, USA. The official updated replacement for the widely respected MM-001, the MM-002 delivers an exceptionally clean and neutral MM phono stage in a compact metal housing that shields the delicate phono signal from electromagnetic interference. It provides 40 dB of gain with a precisely implemented RIAA correction curve accurate to ±0.3 dB, a signal-to-noise ratio exceeding 86 dB, and distortion below 0.015%, all driven by an external 24V DC power supply that keeps transformer magnetic fields away from the audio circuit. The MM-002 is the ideal solution for connecting any MM-equipped turntable to modern amplifiers, receivers, or powered speakers that lack a dedicated phono input.

Proven Analog Circuit Design and Low-Noise Operation

The MM-002 is built on a classic, proven analog circuit philosophy using high-quality components selected specifically for reliability and sonic performance in a phono amplification context. The RIAA equalization is implemented with a precision of ±0.3 dB across the audio band, ensuring the tonal balance of vinyl playback is restored accurately without the frequency response deviations that can make lower-quality phono stages sound thin, bright, or bass-heavy. The 40 dB gain figure is correctly matched to the typical output range of MM cartridges, which produce between 3.5 and 6 mV and require amplification to standard line level for input to an amplifier. The external 24V DC power supply is a deliberate design choice: by physically removing the power transformer from the chassis, the magnetic interference field of the transformer is kept completely away from the sensitive amplification circuitry, directly reducing the hum and noise floor of the unit.

Compact, Shielded Metal Chassis and Simple Integration

The MM-002's matte black metal housing is both practical and effective. Metal construction provides a Faraday shield around the audio circuit, blocking external electromagnetic interference from household electronics, power supplies, and radio-frequency sources that could otherwise couple into the high-gain phono amplification circuit as audible hum or noise. The compact dimensions of 100 x 45 x 93 mm allow it to be placed discreetly near the turntable or behind the amplifier without occupying significant rack space. Setup requires only the connection of the turntable's RCA cables and the power supply, with no switches or adjustments to configure for standard MM operation.

Frequently Asked Questions

What is the Thorens MM-002?

The Thorens MM-002 is a compact moving magnet phono preamplifier from Thorens and the updated replacement for the MM-001. It provides 40 dB of gain, ±0.3 dB RIAA accuracy, a signal-to-noise ratio over 86 dB, distortion under 0.015%, an external 24V DC power supply, and a shielded metal chassis measuring 100 x 45 x 93 mm. It is available at Vinyl Sound in Buffalo, NY, USA.

How does the Thorens MM-002 compare to the Pro-Ject Phono Box S2 or iFi Zen Phono?

The Pro-Ject Phono Box S2 and iFi Zen Phono are both competent entry-level to mid-range phono stages. The Pro-Ject Phono Box S2 offers MM and MC compatibility and adjustable load impedance. The iFi Zen Phono offers gain and loading options for both MM and MC in an affordable format. The Thorens MM-002 is focused exclusively on MM, but its external power supply approach, which the iFi Zen and Phono Box S2 do not use, keeps transformer interference further from the audio circuit. For listeners committed to MM cartridges, the MM-002's dedicated MM design with external PSU represents a clean, purpose-built approach with excellent measured performance at its gain and RIAA accuracy specifications.

Do I need the MM-002 if my amplifier already has a phono input?

If your amplifier's built-in phono stage is already performing to your satisfaction, the MM-002 may not be necessary. However, built-in phono stages in modern amplifiers are often minimum-specification designs that prioritize compactness and cost over sonic performance. The MM-002's dedicated external design, shielded chassis, and external power supply typically deliver lower noise and more accurate RIAA correction than integrated phono stages in the same price range of amplifier. The improvement is most noticeable with higher-resolution MM cartridges such as the Ortofon 2M Bronze or Nagaoka MP-200.

Is the MM-002 suitable for use with USB turntables?

Yes, the MM-002 can be connected to a USB turntable's analog output for playback through a traditional amplifier, improving on the built-in phono stage quality of the USB deck. However, if the goal is specifically vinyl digitization to a computer, the MM-002 has no digital output and cannot perform this function. For digitization, the Thorens MM-008 ADC, which includes an integrated 24-bit / 96 kHz USB ADC, is the appropriate Thorens solution.

What MM cartridges pair well with the Thorens MM-002?

The MM-002 is compatible with the full range of moving magnet cartridges. Well-matched options at different levels include the Ortofon 2M Red or Audio-Technica AT-VM95E at the entry level, the Ortofon 2M Blue or Nagaoka MP-110 at mid level, and the Ortofon 2M Bronze or Nagaoka MP-200 at the premium end. The MM-002's precise RIAA equalization and low noise floor reward higher-performance cartridges with improved resolution and tonal accuracy.
