Ortofon ST-70 Moving Coil Step-Up Transformer

One of the standout features of the Ortofon ST-70 is its use of high-quality Lundahl™ transformers, surrounded by specialised mu-metal shielding. This combination ensures that every detail in a complex array of notes is reproduced with absolute purity, free from internal and external sources of interference. The result is an incredibly quiet and revealing transformer that will impress even the most critical listeners.

But the Ortofon ST-70 isn’t just about technical prowess. Its dual mono design provides discrete circuitry for each channel, eliminating crosstalk and potential distortions. This means cleaner, clearer sound reproduction with a significantly increased stereo imaging. No matter what type of music you’re listening to, the Ortofon ST-70 delivers an expansive stereo separation that brings a lifelike realism to your listening experience.

The Ortofon ST-70 also boasts high-quality industrial-grade PCB, as well as gold-plated RCA jacks with Teflon insulation. These features work together to minimize signal degradation and maximize signal flow, ensuring optimal conductivity for high-quality interconnects. Furthermore, the unit is assembled with minimal internal wiring, preserving the absolute integrity of your signal.

In terms of functionality, the Ortofon ST-70 offers compatibility with most Moving Coil cartridges, with internal jumpers to select between two gain/impedance options. This allows for flexibility while maintaining a clean and sleek aesthetic.

For those considering using the Ortofon ST-70 with the Cadenza Series, rest assured that this transformer is a perfect partner. Not only does it provide the necessary gain for MC cartridges, but it also offers exceptional noise performance and sound quality, making it a superior choice over MC phono preamplifiers.
