The Ortofon ST-M25 Moving Coil Transformer is a specialised device engineered specifically to enhance the performance of SPU Mono CG 25 Di Mk II & SPU Mono CG 65 Di Mk II cartridges. These cartridges due to their low voltage output are incompatible with the MM -INPUT terminal of amplifiers or phono-equalisers leading to an unsatisfactory sound volume. Addressing this issue the ST-M25 has been meticulously designed to boost the voltage by 12d B ensuring compatibility with standard MM inputs. This unique transformer provides a seamless connection between the cartridge & amplifier optimising audio output for an immersive listening experience. The cartridges provide a consistent monaural sound from both L/R channels. For optimal performance its recommended to connect the L/R channels of the cartridges through the ST-M25 & amplifier to the final output "speakers (L/R)". This setup allows listeners to revel in the rich vibrant sound of monaural audio emanating from both speakers. The Ortofon ST-M25 Moving Coil Transformer ensures your audio system delivers its full potential providing a robust & immersive sound experience. ...

The Ortofon ST-7 is an MC transformer that serves as a useful asset for Moving Coil (MC) cartridge owners. MC transformers are designed to maximise the efficiency of both the cartridge & the phono stage. As a result of their design MC cartridges exhibit a lower output than Moving Magnet cartridges. This necessitates a higher gain from a phono stage for standard listening levels on your audio system. Unlike phono stages which have a steady resistive input impedance MC transformers possess an input impedance that varies with frequency. These transformers are passive thereby minimising the effects of external electrical forces on the cartridges low output signal. The unique design of the transformer allows it to amplify the MC output level while reducing harmonic distortion as the frequency increases creating a purer electrical signal & enhancing sound performance. Encased in robust housing with a compact & stylish design the ST-7 is supported by four rubber feet to minimise unwanted vibrations. Intricate internal wiring & gold-plated terminals ensure optimal signal transmission. An innovative sandwich winding structure enhances high-frequency response & delivers clear open sound across all frequencies. The dual-mono design with individual shielding for each channel improves imaging & minimises environmental noise impact. Perfectly compatible with MC Quintet Series SPU Classic models & SPU 1 models the ST-7 transformer is a valuable addition for vinyl enthusiasts seeking the best possible sound. ...

The Ortofon ST-70 is a moving coil (MC) signal transformer combining superior components with world-class engineering to deliver unparalleled sonic fidelity. It is equipped with Lundahl transformers encapsulated within specialised mu-metal shielding. This design ensures every musical nuance is delivered with absolute purity free from both internal & external interference; this a combination that renders the ST-70 one of the most silent yet revealing transformers in existence. The ST-70s dual mono design offers discrete circuitry for each channel eradicating crosstalk & potential distortions for cleaner clearer sonic reproduction. This enhances stereo imaging significantly providing stereo separation that conveys lifelike realism & accurate tonal balance without colouration. Incorporating premium PCB to minimise sonic degradation & maximise signal flow the ST-70 also features gold-plated RCA terminals with Teflon insulation for optimal conductivity. The unit is assembled with minimal internal wiring ensuring absolute signal integrity. Offering compatibility with most moving coil (MC) cartridges the ST-70 features internal jumpers that automatically select between two gain/impedance options. Transformers are essential for the best MC cartridge performance due to their low output requiring higher gain provided by step-up moving coil transformers or MC phono preamplifiers. Despite performing similar functions these devices differ fundamentally in function & sonic character. Step-up moving coil transformers are often preferred for their low noise & distortion properties as well as their excellent sonic integrity thanks to their completely passive operation. ...

The Ortofon ST-80 SE Moving Coil Transformer has been engineered to boost the signal of your MC cartridge & create accurate sonic reproduction through your Hi Fi system. This Special Edition transformer outperforms existing models with its larger bobbin increased layers in the permalloy core & additional coil windings. Housed in a magnetic shield of permalloy each transformer is encased in a robust 10mm thick metal cylinder machine carved from a solid block of aluminium. This heavy metal casing effectively buffers environmental noise providing a pure & unadulterated audio experience. Offering ultimate stability thanks to its large weight & rubber feet the ST-80 SE stays firmly in place ensuring uninterrupted signal transfer. Designed as a pure dual mono model the ST-80 SE guarantees optimal channel separation. It features internal point-to-point wiring made from Teflon-insulated solid-core OFC copper wire plated with gold & high-quality gold-plated RCA terminals with Teflon insulation ensuring the highest integrity in signal transmission. The ST-80 SE pairs perfectly with most top-tier MC cartridges including the Cadenza & Exclusives series (Xpression MC Anna MC A95 MC Windfeld Ti MC Century) the historical MC A90 & MC Windfeld & the SPU cartridges.
