To further minimize 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.

The ST-70 maintains compatibility with most Moving Coil cartridges by using internal jumpers to select between two gain/impedance options. This affords audiophiles with broad flexibility while still maintaining a clean aesthetic.
The ST-70 transformer is the perfect partner for e.g. the Cadenza Series.
Why use a transformer? Since the output of MC cartridges is low, higher gain is required to utilize it, such as that provided by Step-up moving coil transformers or MC phono preamplifiers. Although both devices provide this requirement, both are fundamentally different in function and in sonic character. This is where Step-up moving coil transformers are frequently seen as superior; they are completely passive and offer exceptional noise performance and sound quality.
