Ortofon ST-7 Moving Coil Step Up Transformer 

Step-Up Transfomer

Compact and stylish, the ST-7 has a solid housing supported by four rubber feet, which helps to reduce unwanted vibrations in the unit.

High quality internal wires together with high quality gold plated terminals provide the optimum signal transmission. The sandwich winding structure, used in the ST-7, 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 and the SPU Classic models.

Running my Project Evo Classic with Ortofon Quintet Red through Cambridge Audio duo phono stage to my Arcam home theatre amp. Facebook group suggested adding step up transformer as phono stage was weakest link. Got the older model for great price, less than 5 mins set up, and now running MC cart on MM settings thanks to ST-7. Much improved sound and will likely upgrade to Bronze Cart in time. Very happy
