Moving Coil Step Up Transformer

The AN-S5 is an Ultra high quality moving coil step up transformer copper wired on large super mumetal 250 core fully interleaved, two single impedance versions available, low and high.

All low versions should be used with Audio Note™ MC cartridges to get best bandwidth and dynamic conversion to retain harmonic envelope best possible.

It is important to appreciate the utmost importance of getting the impedance matching between the cartridge coil and the primary of the transformer as close as possible, we used to sell a transformer, the AN-S7, which had 6 switchable impedances, which was a great help when determining which impedance suited a cartridge best, however, the trade-off in sound quality from the multible taps on the transformers and the switches were too great.

All Audio Note™ MC transformers are housed in solid copper chassis’s for best sound. Despite this they are quite sensitive to positioning, and hum will occur when they are too close to power cords, supplies or electric motors and their associated wiring (from a separate turntable power supply to the turntable itself for example), so careful positioning is mandatory.
