The ST-80 Special Edition Moving coil transformer delivers a detailed reproduction with a touch of warmth accompanied by a full bodied sound quality. Compared with existing models, ST-80 SE has a larger bobbin, more layers in the permalloy core and more coil windings.

 

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 1.5 kg, ensuring it stays in place even when cables are attached.

The ST-80 SE is built as a pure dual mono model, which ensures maximum channel separation. Internal point-to-point wiring is made by Teflon insulated, solid-core pure OFC copper-wire plated with gold. Together with high quality gold plated RCA jacks with Teflon insulation that ensures the optimum signal transmission and integrity.

 

The ST-80 SE will be a perfect match to most high quality MC cartridges, such as the Cadenza series, Exclusives series (Xpression, MC Anna, MC A95, MC Windfeld Ti, MC Century), also the historical MC A90 and MC Windfeld, as well as the SPU cartridges.

 

The combination of the Xpression, ST-80 SE and TA-110 tonearm gives a supreme experience!

Why use a transformer?

Step-Up Transformers (SUT) are a serious option for anyone who owns a Moving Coil (MC) cartridge, one that can significantly improve both the sound quality and sonic character.  Quite simply, a good transformer is the best way to audition an MC cartridge with the highest performance possible.

Since the output of MC cartridges is lower than that of a Moving Magnet (MM), higher gain is required to utilize them, such as that provided by SUTs or MC phono preamplifiers.  Although both devices provide this requirement, both are fundamentally different in function and in sonic character.  This is where SUTs are frequently seen as superior; they are completely passive and offer exceptional noise performance and sound quality.

This is due to the fact that the structure of harmonic and intermodulation distortion is fundamentally different between MC-preamps and SUTs. While an MC pre-amplifier has a constant resistive input impedance, an SUT has an input impedance that is frequency dependent. The harmonic distortion produced by SUTs is highest at the lowest frequencies and drops as the frequency rises, whereas in most MC preamps the distortion increases as the frequency rises.  Combined with significantly lower Intermodulation Distortion (IMD), the sound produced with an SUT will be much more open, dynamic, spacious, and natural.
