Push-pull circuit further refined from Overture

 

The first stage and driver stage are direct coupled, and a new generation pure silver foil capacitors with vibration suppression are used for coupling with the output stage. Moreover, the low impedance design of the whole circuit is aimed the direct sound performance. The output stage continue to employ CCB (constant current bias circuit). The music signal is prevented from flowing into the bias adjustment VR, enabling pure signal transmission.

 

Optimized wiring

 

Internal wirings are skillfully arranged so that shortest paths and best performance are obtained. SSW (Silk Silver Wire) are used for internal wirings. Ls-41 are used for paths in which shielding are needed.

 

Super High Quality Parts

 

All parts were carefully chosen after massive hours of listening tests. Silver foil capacitors, silver lead resistors, SSW silk silver wires, Ls-41 shield cable, Audio Note custom made output transformers and power transformer. All CR part are carefully selected and arranged.
