Know before you buy
By pairing a solid-state input stage with a 300B tube output stage, the 300p achieves the rich, harmonic texture of tubes while maintaining the low noise floor and tight bass control typically associated with solid-state designs.
While 20 watts is modest, the 300p is engineered with proprietary wideband output transformers that provide surprising grip and control. It performs best with high-to-medium sensitivity speakers, though it is capable of driving a wide range of impedances.
The modulometer is a signature Nagra feature that allows you to monitor the amplifier's performance and output levels in real-time. It provides a visual confirmation of signal integrity and adds to the classic aesthetic inspired by Nagra’s professional field recorders.
As a tube amplifier, the 300p requires standard care regarding tube life and ventilation. It comes with the Nagra VFS (Vibration Free System) platform, which is essential to place the unit on to minimize mechanical interference and ensure optimal performance.
Yes, the 300p features user-selectable RCA and XLR inputs, allowing you to choose the connection type that best suits your preamplifier or source components.
No, the 300p is not rack-mountable. It is designed as a standalone heirloom piece that requires its own dedicated space and proper ventilation to operate safely and effectively.
