Almost 20 years after the release of the mythical preamplifier Nagra PL-P in 1998, Nagra is releasing the one of the most ambitious projects of its history, the HD PREAMP. The Nagra R&D Department, served by ten skilled and specialized audio engineers, worked on this project for the past three years with the goal of creating the most revealing and engaging preamplifier in the world. The Audio engineers spared no expense or limitation developing electronics, mechanics, power supply and addressing thermal and vibration issues. Each stage of the design also included extensive listening sessions. The result is a striking product in terms of appearance, specification and performance. It will just reshape the expectation you may have of what a preamplifier will add to your whole set-up, sources and amplifiers…TECHNICAL SPECIFICATIONS
