It pairs exceptionally well with the MC Quintet Series, SPU Classic models, and SPU #1 models, making it a versatile addition to any audiophile's collection. This versatility allows users to explore different cartridge options without worrying about compatibility issues.

Dual Mono Design

The ST-7 features a dual mono design, where each channel is individually shielded by a permalloy housing. This design reduces cross-talk and interference from environmental noise, resulting in improved imaging and a more accurate stereo soundstage. The separation of channels ensures that the left and right audio signals are transmitted with minimal overlap, preserving the integrity of the original recording.

Sandwich Winding Structure

A key technical aspect of the ST-7 is its sandwich winding structure, which significantly enhances the transformer's high-frequency response. This structure contributes to a sound that is both clear and open, with excellent detail across the entire frequency spectrum. The result is a more dynamic and lifelike audio experience that brings out the best in your vinyl records.

Compact and Stylish Design

The ST-7 is not only functional but also aesthetically pleasing. Its compact design allows it to fit easily into any audio setup, while the solid housing is supported by four rubber feet to minimize vibrations. This construction helps reduce unwanted noise and ensures the transformer remains stable during playback. The stylish design complements the high-quality build, making the ST-7 a visually appealing addition to your audio system.

High-Quality Components

Ortofon has equipped the ST-7 with high-quality internal wires and gold-plated terminals to ensure optimal signal transmission. These components are carefully selected to preserve the purity of the audio signal, minimizing losses and distortions that can affect sound quality. The result is a step-up transformer that delivers a clean and precise signal from your MC cartridge to your phono preamplifier.
