110V/220V Silvery X9 Flagship Version HiFi Electronic Tube Power Amplifier Hi-end Preamplifier 40W

110V/220V Silvery X9 Flagship Version HiFi Electronic Tube Power Amplifier Hi-end Preamplifier 40W

Description:
- The X9 is positioned as a high-end HIFI preamplifier, designed and developed by the American SHIYATU and Yong Heng Zhi Yin. A good preamplifier cannot be achieved without good circuits and high-level design and tuning. The X9 tube preamplifier circuit integrates the advantages of many high-end brand and famous computer circuits, and the design and development process takes up to 3 years, after countless improvements and debugging.
- Electronic tubes have a large dynamic range, fast conversion rate, and their amplification circuit has better open-loop performance than transistors. They can operate stably without the need for deep negative feedback or phase compensation capacitors. Therefore, their dynamic performance is better. Overall, the sound quality of electronic tubes is full, soft, warm, pure, beautiful, rich in harmonics, rich in musical charm, soft and clear in low frequencies, and fine and smooth in high frequencies. Human voice is also a major advantage of electronic tubes.

Features:
- The aircraft grade aluminum alloy body is made of imported CNC precision machining, and the surface is treated with high-end sandblasting and oxidation technology.
- Pure copper gold-plated wiring base minimizes transmission loss and restores the essence of sound. Two sets of RCA output ports per channel, 4 x RCAs, and 4 x XLRs (balanced). One channel can connect multiple rear stage amplifiers and achieve split tone gameplay.
- X9 uses two imported ring-shaped transformers as the power supply, specifically designed for electronic tubes. The power transformer is completely isolated from the circuit board, and the transformer is treated with a high-strength shielding cover. Combined with a high-frequency common mode filter, it avoids transformer magnetic field interference, removes ripple interference in the power supply, and provides a purer power system, achieving no interference, low noise, pure music background, clean and natural sound.
- Electronic tubes are important components in the tube preamplifier, which are related to sound quality. The X9 adopts a high-end series of electronic tubes imported from Russia, with reliable quality and a service life of 20-30 years, superior performance, high sound density, rich homophones, wide sound range, wide sound field, clear high-frequency layers, clear secondary sensation, full air feeling and full and smooth, providing a wonderful listening experience.
- The X9 adopts the HIFI recognized enthusiasts level ALPS motor potentiometer as the volume potentiometer, with reliable and durable quality, low loss, high sound reproduction, precise positioning, damping, smooth hand feel, and high consistency in balance.
- The HIFI true balance simulation Class A module jointly developed by China and the United States is comparable to the materials used in high-end audio circuits of millions-level.
- Original imported electronic tube specific resistor for Panasonic with stable performance and reliable quality.
- German imported audio enthusiasts capacitor for WIMA with fast speed low loss, and natural balance of sound quality.
- Schottky Barrier Diode has fast rectification speed, low loss, high efficiency, and smooth and clean power supply.
- Imported enthusiasts grade supplements such as filter capacitors and good power supply are the foundation of good sound, with high sound density, clean and clear, smooth and mellow.
- Adopting for Mundorf mcap MKP high-end infinite capacitors and supplements.
- The core technology - balanced circuit, making the sound more transparent and full, and the sound field wider and more balanced; It can provide larger, more dynamic, and longer transmission distances.
