Thorens SPU 124 Moving Coil Cartridge at Vinyl Sound Buffalo, NY USA

The Thorens SPU 124 is an SPU-style moving coil phono cartridge from Thorens (Lahr, Germany), developed in close collaboration with the legendary Danish cartridge manufacturer Ortofon and available at Vinyl Sound in Buffalo, NY, USA. Purpose-built as the optimal cartridge companion for the EISA award-winning Thorens TD 124 DD turntable and its TP 124 tonearm, the SPU 124 modernizes the classic Ortofon SPU design with key refinements for contemporary analog systems. A revised generator system delivers a maximum output of 0.5 mV, relaxing the high-gain requirements that original vintage SPU cartridges impose on phono preamplifiers. A highly polished nude elliptical stylus with significantly reduced tip mass improves both groove tracking accuracy and high-frequency retrieval compared to the vintage original, while retaining the deeply rich and tonally authoritative sonic character for which SPU cartridges have been celebrated since 1959.

The SPU Legacy and the TD 124 DD Collaboration

Ortofon's SPU, or Stereo Pick Up, was introduced in 1959 as a professional broadcast cartridge and became the standard in European radio stations and the preferred choice of demanding music listeners for decades. Its distinctive character, heavy and warm in the low frequencies with exceptional dynamic authority and tonal weight, made it one of the most musically satisfying cartridge designs ever produced. The challenge of the original SPU for modern audiophiles is its very low output voltage, typically 0.2 mV, which demands extremely high-gain phono preamplification, and its high tracking force requirements, which can stress modern lightweight tonearms. Thorens and Ortofon developed the SPU 124 specifically to resolve these limitations while preserving the character that makes the SPU design irreplaceable. The result is a cartridge that maintains the warm, weighty, dynamically alive presentation of the classic SPU in a form compatible with contemporary high-end phono stages and the precision-adjusted TP 124 tonearm.

Nude Elliptical Stylus and Modern System Compatibility

The SPU 124 is equipped with a highly polished nude elliptical stylus, where the diamond is shaped directly rather than bonded to a metal shank. The reduced tip mass of the nude construction, combined with the elliptical contact geometry, provides meaningfully better groove tracking and high-frequency retrieval than the vintage SPU's original spherical stylus, while remaining compatible with the wide range of record pressings including older mono and early stereo LPs that the SPU was born to play. The 0.5 mV output is high by MC standards, allowing it to be used with MC phono stages that do not require the extreme 60 to 70 dB gain needed for 0.2 mV vintage SPU designs. The included heavy counterweight for the TP 124 ensures correct tracking force application and tonearm balance for this high-mass cartridge type.

Frequently Asked Questions

What is the Thorens SPU 124?

The Thorens SPU 124 is an SPU-style moving coil cartridge co-developed by Thorens and Ortofon specifically for the TD 124 DD turntable and its TP 124 tonearm. It delivers a maximum output of 0.5 mV via a revised generator system, features a highly polished nude elliptical stylus with reduced tip mass, and retains the rich, tonally authoritative character of the classic Ortofon SPU design. It is available at Vinyl Sound in Buffalo, NY, USA.

How does the Thorens SPU 124 compare to a vintage Ortofon SPU Classic?

A vintage Ortofon SPU Classic typically produces 0.2 mV output, requires a tracking force of 3.0 to 5.0 g, and uses a spherical stylus that cannot resolve fine groove detail as effectively as the SPU 124's nude elliptical tip. The SPU 124's 0.5 mV output requires a less extreme MC gain stage, and its reduced tracking force demands are more compatible with modern precision tonearms like the TP 124. The SPU 124 retains the classic SPU's warm, weighty, dynamically authoritative tonal signature while delivering substantially improved tracking accuracy and easier system integration. For collectors wishing to experience the SPU sound on a modern TD 124 DD system without the operational demands of a vintage SPU, the SPU 124 is the definitive system-matched choice.

What phono preamplifier gain do I need for the Thorens SPU 124?

The SPU 124's 0.5 mV output is at the high end of the low-output MC range, often described as a medium-output MC. A phono preamplifier with MC gain of approximately 50 to 60 dB is appropriate, a lower requirement than the 60 to 70 dB needed for standard 0.2 mV MC cartridges. The Thorens MC 1600 phono preamplifier, with its adjustable gain from 32 to 68 dB and adjustable MC load impedance from 20 to 1280 ohms in over 60 steps, is an ideal system-matched partner for the SPU 124.

Can the Thorens SPU 124 be used with tonearms other than the TP 124?

Yes. The SPU 124 uses a standard SME connector and can be mounted on any tonearm compatible with the SME bayonet standard. However, SPU-type cartridges are high-mass designs that require a tonearm capable of balancing them correctly, typically a medium-to-heavy arm in the 14 to 25 gram effective mass range. The TP 124 tonearm in the TD 124 DD system is specifically designed and includes the appropriate heavy counterweight for the SPU 124. Compatibility with other tonearms should be confirmed by checking that the total cartridge and headshell mass falls within the counterweight range of the specific arm.

Is the SPU 124 suitable for older mono records?

Yes, with the important caveat that the SPU 124 is a stereo cartridge and plays stereo records in the standard configuration. For mono records, a dedicated mono cartridge is the ideal choice because it responds only to lateral groove modulation and ignores vertical noise introduced by pressing defects and groove wear. However, the SPU 124's warm tonal character and its heritage in the Ortofon SPU lineage, which was widely used for mono playback in professional broadcast settings, make it a musically satisfying choice for late mono and early stereo pressings when a dedicated mono cartridge is not available.

Where can I buy the Thorens SPU 124 in Buffalo or the USA?

The Thorens SPU 124 MC Cartridge is available at Vinyl Sound in Buffalo, NY, USA. Vinyl Sound is an authorized Thorens dealer providing full cartridge setup, tonearm alignment, and product support for the complete Thorens and Ortofon range across Western New York and the United States.
