The Ortofon ST-70 is reserved for discerning audiophiles and music lovers. The ST-70 combines the fine components, along with world-class engineering, for unparalleled sound reproduction.

Starting with high quality Lundahl™ transformers, surrounded by a specialized mu-metal shielding, listeners can be assured that every detail in a complex array of notes is reproduced with utter purity, with freedom from internal and external sources of interference. These two items combined make the ST-70 transformer one of the quietest, most revealing transformers.

Accurate Tonal Balance

Featuring dual mono design, the ST-70 provides discrete circuitry for each channel, resulting in the elimination of crosstalk and possible distortions. This results in cleaner, clearer reproduction with substantially increased stereo imaging. Regardless of the composition being played, the ST-70 expansive stereo separation provides lifelike realism and accurate tonal balance devoid of colouration.

Terminal Connections

To further minimise signal degradation and maximize signal flow, the ST-70 has been engineered using high quality industrial grade PCB. Additionally, gold-plated RCA jacks with Teflon insulation provide optimal conductivity for use with high quality interconnects. Internally, the unit is assembled with an absolute bare minimum of internal wiring, preserving absolute signal integrity.
