Dit State-of-the-Art element kenmerkt zich door drie belangrijke eigenschappen: het maakt gebruik van geavanceerde SLM technieken, 2: modificatie van het generatorsysteem en 3: de Ortofon ontwerptraditie. SLM staat voor Selective Laser Melting en maakt het mogelijk dat onderdelen in verschillende materialen direct van de ontwerptafel geproduceerd kunnen worden. Deze tijdswinst gecombineerd met een grotere vrijheid in geometrische vormen, geven het geavanceerde ontwerp met de unieke resonantievrije eigenschappen. Voorheen zou dit fabricageproces jaren langer hebben geduurd en de materiaalkeuze veel beperkter zijn. Door het unibody-ontwerp kan het element niet verkeerd in de headshell geplaatst worden. Dit prachtige element combineert excellent met de TA-110 en TA-210 toonarmen van Ortofon.
Introduction
The Ortofon Xpression is a modern High-End cartridge with a standard headshell connector. The state of the art product, the Ortofon Expression represents a combination of three following elements very characteristic for Ortofon:
- The cutting edge SLM materials technology pioneered by the MC A90 and SPU 90th Anniversary
products
- Modification of the generator system introduced with the MC A90 and the MC Windfeld
- Ortofon design tradition
The Xpression cartridge bridges the gap between SPU-type cartridges and High-End cartridges like the MC A90 and the MC Windfeld designed for headshell mounting. The result is a high-performance moving coil cartridge with the convenience of a standard headshell connector, which provides a simple and elegant method of directly connecting the generator and tonearm via the Xpression’s one-piece body. Since the cartridge length is identical to that of an SPU, the Xpression can easily be fitted onto a large selection of tonearms without additional concern for proper alignment. The cartridge height is also identical to that of an SPU, making further VTA adjustments unnecessary. Additionally, the mass and compliance properties of the Xpression ensure that a proper match will be achieved with most SPU-compatible arms, including the new Ortofon TA-110 and TA-210 tonearms. Finally, the Xpression features a Boron Cantilever and a special polished Replicant 100 diamond, found also in the MC A90 and the MC Windfeld cartridges, providing more responsive and transparent sound reproduction.
High-end materials benefit new coil technology
Using expensive Aucurum coils of gold-plated, 6NX oxygen free copper allows for zero-loss transmission of the diamonds movements via its boron cantilever. This combination combines low moving mass with an extremely high degree of rigidity. The specially designed armature achieves an extreme precision in each coil turn in all layers. This enables the Xpression to obtain a higher degree of channel separation, while simultaneously offering lower distortion and better channel balance. A low output impedance of 4 Ohm and a medium output voltage of 0.3 mV make the Ortofon Xpression a perfect partner for most phono preamps and step-up transformers, including the new Ortofon ST-80 SE.
Design
The presentation of the Ortofon Xpression is a continuation of the new paradigm in engineering and manufacturing introduced by the MC A90. Because total freedom from resonance in the audible frequency range is a precondition for optimal sound quality, the design of the Xpression has been dictated by the complete elimination of unwanted resonance. Arguably the most exciting development in the Xpression is the introduction of our custom SLM manufacturing process. The bottom cover has been constructed from a special proprietary TPE (Thermo-Plastic Elastomer) material, which provides extremely high damping. Also included is an easy-to-grab finger lift as well as a simple-to-use stylus guard. When combined with Ortofon’s world-class knowledge in analogue sound reproduction, the Xpression will undoubtedly provide sound which is literally unsurpassed and simply has to be experienced.
