The main amplifier circuit of the whole machine is based on the famous Swiss machine “Crescent Scimitar” worth 130,000 yuan. The dartzeel NHB-108 amplifier uses a large loop feedback amplifier circuit, which completely eliminates the influence of the speaker’s back electromotive force on the amplifier. The sound is natural, comfortable, and has strong control. The actual driving force is better than the large Class A machines I have heard before, such as KSA50.
The highly acclaimed NHB-108 minimalist broadband circuit, the wonderful revolutionary design has a strong current output capacity. There is no global negative feedback, no negative feedback or compensation network in the input and output stages, and the output stage is open-loop design. There are only 6 transistors per polarity in the entire signal path. The latest darTZeel SCNP enhanced version provides better signal timing and huge current peaks.
The production process uses a silver-tin wire white light soldering station without static welding. Distortion, signal-to-noise ratio, separation, and sound audition are all checked by a dedicated person to ensure that there is nothing wrong.
Product parameters
Input impedance: 100K ohms
Line gain: +26dB
Total harmonic distortion + noise: -100dB@no load; -60dB @8ohm
Separation: -125dB
Signal-to-noise ratio: 115dB
Frequency response: 10Hz 20KHz
Output power: 140W @8ohms; 200W @4ohms
Weight: 28KG
Dimensions: Width 440mm*Depth 380mm (plus front and rear handles 410mm)*Height 160mm
Configuration Description: Dual-channel direct-print version: Direct-print chassis, 350mm internal depth, default aluminum alloy top cover (please contact customer service for confirmation if a brown acrylic top cover is required), 4 American Spey or BC75V39000UF capacitors.
Materials: 1. High-quality replica all-aluminum chassis, direct-print version weighs approximately 26kg, exquisite appearance.
2. Two oxygen-free copper 300W toroidal transformers, independent power supply for left and right channels, ensuring sufficient separation and power.
3. Classic version uses a filter array composed of 16 original ELNA-AUDIO 10000UF capacitors; direct-print version uses 4 Spey or BC 75V39000UF capacitors; Japanese Omron speaker protection circuit and high-power soft-start circuit. This ensures both the machine and speakers operate in a safe state.
