The MASTER range : Absolute perfection...
A high quality power supply R-Core designed separated from the signal gain stages which improve the details and keep the sound stage more better.
Fully balanced design, the gain stages and pre-driver stages work in Class A, built with discrete analog stages without any OPA or coupling caps in the signal channels.
The output transistor stages work in high idle current state.
