The ST-90 Moving coil transformer delivers a detailed reproduction with a touch of warmth accompanied by a full bodied sound quality. The frequency response is wide and flat.
The transformer is magnetically shielded in a permalloy case, which in turn is inserted into a robust 10mm thick aluminum cylinder bored out of a solid aluminum block. Together with the heavy metal case the transformer effectively isolates against environmental noise.
The stability of the transformer is superb thanks to its substantial weight of 2kg
Equipped with XLR terminal for full balance connectivity as well as common RCA plug terminal.
The ST-90 will be a perfect match to most high quality MC cartridges, such as the Cadenza series, the MC A90, the MC Windfeld, the Ortofon Xpression, MC Anna, MC A95 as well as the SPU cartridges.
