The heart and soul of a system that inspires.
The most advanced preamplifier ever designed.
With its groundbreaking signal path technology, battery power supply and unrivalled phono stages, the NHB-18NS is still the benchmark for preamplifiers.
The DarTZeel 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.
darTZeel has always developed the most rapid audio circuits.
The NHB-18NS’s unique circuit board layout allows each optical input to be activated separately.
The absence of global negative feedback ensures an ideal and uncompromising listening experience.
darTZeel’s NHB-series represents the pinnacle of musical reproduction. Its products are designed and built like works of art.
For the NHB series, each aluminium component is milled from a solid block, hand-finished, brushed and anodised.
This underlines the uniqueness and exclusivity of the NHB series.
