The most advanced preamplifier ever designed.
With its groundbreaking signal path technology, battery power supply, and unrivaled phono stages, the NHB-18NS is still the benchmark for preamplifiers.
The NHB-18NS is peerless in terms of clarity and musicality. Designed to control NHB-series power amplifiers, it offers state-of-the-art preamplification and control.
50-ohm darT-to-Zeel connection cables complete this exquisite offering.
Simple and efficient
Machined from a solid block and held comfortably in your hand, the NHB-18NS remote control provides access to its key functional features.
Inside view
