Description Ortofon Hi-Fi ST-7 MC Transformer The Ortofon Hi-Fi ST-7 MC Transformer has a sandwich winding structure. This significantly improves the high frequency response and provides a very clear and open sound over the whole frequency range. Additionally, the dual-mono design, including the individual shielding of the two channels, improves the imaging of the transformer and reduces the influence of environmental noise. The ST-7 transformer will be a perfect match for, among other MC cartridges, the MC Quintet Series, the SPU Classic models and SPU #1 models.
