AN S4

PHILOSOPHY

 

The moving coil step ups in Audio Note land are where the magic happens. The fragile signal comes into its own with the step up, therefore Audio Note offers an extensive range of step-up transformers, each with different 'loading' options to make possible the best results with (our) moving coil cartridges. The (impedance) matching of the transformer with the cartridge (and phono-preamplifier) is for many a complex subject, and its best to ask us to suggest the optimum solution as you will find much ill-informed advice on the internet.

 

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.

 

The different types of MC Transformers each have different wiring material (copper/silver), wiring topology (diameter/ratio/interleaving) and core’s (material/size/laminate thinkness), resulting in better performance and higher gain as we move to the higher levels.

 

Our ‘top of the line’ AN S9 uses very large transformer cans wound in silver on interleaved, 0.1mm laminate super mumetal 250 cores, copper-clamped to the chassis. The transformers are hard wired with Audio Note Pallas output cables, though alternative cables or RCA connectors can be specified to the customer’s choice. 

 

The S9 is available in three versions, each with a set input impedance. Alternative, custom-manufactured loadings can be specified at no additional charge.
