Super power supply: the main power supply adopts super large 1600 VA transformer and up to 8 expensive large scale customized mundorf capacitors. The super power supply ensures the stability of the amplifier and can provide high power at any time. In addition, it is equipped with Nagra's specially designed  filter to ensure the extremely stable voltage rail of the amplifier, and the dual PI filter is used as HD The protective shield between the AMP and the power supply ensures that the current consumption from the HD amp is not contaminated by the pulse signal.

Nagra is precisely paired with MOSFET field effect transistors to ensure the purest reproduction and the closest sound to the tube.

Nagra has always adhered to the philosophy of simplicity, the input amplifier stage adopts a minimalist circuit design to ensure transparency and direct fax. The expansion stage is designed and implemented, while the driving stage uses multiple sets of decoupling capacitors to prevent EMI noise interference and convey transparent and direct neutral tone.
