It is becoming increasingly obvious that applying transformer at every stage of an amplifier yields a great benefit in sound quality, provided off course the transformer in question is of an appropriate quality and design.

 

Replacing any coupling capacitor with a well designed and correctly matched driver or interstage transformer yields an almost shocking improvement in sound and should be tried to fully understand what a good wideband transformer has to offer.

 

All Copper – Copper transformers have copper lead out wires, Copper – Silver have copper on the primary and Audio Note silver leadout wires on the secondary and silver naturally silver all round.
