Introduction to Black Widow NHB-268 three internal materials:
1: Each channel uses a 1000W high-level secret custom transformer, which is customized with German A-grade iron core without breakpoint.
The closely related power source comes from the audio-only brand (Furukawa, Japan).
2: The capacity of 12 Siemens 22000U100V large pond capacitors is as high as 132,000 microfarads, which can meet the demand of instant powerful energy and ensure sufficient energy for certification.
3: Fully balanced design is adopted from signal input stage to output, and ON Semiconductor audio dedicated tubes are adopted from input differential to final stage output. The mono final stage has 6 pcs ON Semiconductor high-fidelity audio dedicated high-power tubes, which provide powerful current for the large appetite speakers.
4: The final stage tube uses ON Semiconductor MJL1302/MJL3281 high-power tube, the rear-stage amplifier audio pair tube, the original genuine Abe ON Semiconductor high-power tube, and the output power is 600W per channel. The output power tube is still quite large. The margin is called luxurious and high-end! Promoting a large appetite speaker is easy to do, even if you listen to it at a low volume, you can feel a steady flow of low-frequency volume and rich background sound.
5: Customized 4 oz thick machete PCB capacitor connector
Excellent matching performance: It can easily control the top quality speakers such as ATC, THIEL, B&W, PROAC, Sound of Beauty, Dynaudio, etc. The highest design concept of this unit is the pursuit of sound quality. For many years, Yuanyun has been studying HI from various countries. -The sound characteristics of the END famous machine, and use the sound quality of FM, MBL, Daxiao, Gawain, Guifeng, Mark, K guy and other famous machines in our own audition room as a reference, while maintaining their own sound style characteristics , The sound quality of this (oscillator) machine is carefully adjusted and optimized. To achieve self-satisfaction, equipment suitable for the majority of hobbyists. Bingzhu (your request is my pursuit philosophy) to make Chinese conscience products!
