Audio Note AN-S5 MC Step-Up Transformers (AN-S5L & AN-S5H)

The AN-S5 is the fifth model up in the Audio Note range of step up transformers. Compared to the model beneath it, the S5 features large Super Mumetal 250 cores 

Like the rest of the range, their step up enclosures are made from copper, and there's a substantial copper clamp that secures and damps the transformer enclosures. The mu-metal encased transformers are made by Audio Note using their extensive experience of core materials and winding technology. 

There are two versions available, the AN-S5L where the 'L' for Low, which is intended for very low output and impedance cartridges - primarily the Audio Note Io range.

The AN-S5H where the 'H' stands for High is suited to most other low impedance MC cartridges on the market as it presents a 12 Ohms input impedance.

*It is possible to use transformers with cartridges that have greater internal impedance, or values that are outside the preferred ranges of the switchable inputs, however, it is important to realise that an input impedance in the region of three to four times the internal impedance of your cartridge will usually provide the best results.
