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.
