The Dartzeel NHB-18NS is a high-performance hybrid headphone amplifier and preamplifier from the Belgian audio brand Dartzeel. It combines the functionality of both a headphone amplifier and a line-level preamplifier into a single unit, making it a versatile choice for audiophiles and music enthusiasts.Here's a breakdown of the key features and specifications of the Dartzeel NHB-18NS:1. Hybrid design: The NHB-18NS features an innovative hybrid design that combines the benefits of both tubes and transistors. It uses dual ECC82/12AX7 wound triode tubes in the input stage, followed by a wideband JFET device and high-speed bipolar transistors to provide a fast and dynamic output.2. Step-up transformer: The NHB-18NS uses a high-quality step-up transformer to match the output impedance of the amplifier to any headphone, allowing it to drive even the most difficult-to-drive headphones with ease.3. Dual-mono architecture: The NHB-18NS employs a dual-mono architecture, with completely separate left and right input and output stages. This ensures that each channel delivers its own unique sound, free from any interference or crosstalk.4. Extremely low noise: The Dartzeel NHB-18NS is designed to be extremely quiet, thanks to its high-quality components and careful circuit layout. It has a typical noise floor of only -130dB (A-weighted), making it one of the quietest amplifiers in its class.5. Tube-switching: The NHB-18NS allows you to switch between tube and solid-state operation at the touch of a button, giving you the flexibility to tailor the sound of the amplifier to your preferences.6. Input sensitivity: The NHB-18NS has a very high input sensitivity of 750mV, making it ideal for use with low-output sources such as turntables and tube preamplifiers.7. Output power: The NHB-18NS has a maximum output power of 5W into 32 ohms, which is plenty of power to drive most headphones to comfortable listening levels.In summary, the Dartzeel NHB-18NS is a high-performance hybrid headphone amplifier and preamplifier that combines tube warmth and transistor speed in a versatile and flexible design. Its low noise, high input sensitivity, and dual-mono architecture make it a great choice for audiophiles and music lovers who demand the best possible sound quality from their audio equipment.
