Yong Heng Zhi Yin X9 40W Hifi Tube Preamplifier Class A Tube Preamp (Silver) with Remote Control

Yong Heng Zhi Yin X9 40W Hifi Tube Preamplifier Class A Tube Preamp (Silver) with Remote Control

Features:
- The X9 flagship preamplifier is designed for your discerning ears to create a beautiful and natural sound
- High-quality tubes: The dynamic range of the tubes is large, the conversion rate is fast, and the open-loop index of the tube amplification circuit is better than that of transistors, and there is no need to add deep negative feedback. It can also work stably without phase compensation capacitors. Therefore, its dynamic index is better, and the sound quality of the tubes is generally full, soft, warm, innocent and beautiful, rich in homophony, and rich in musical charm. The low frequencies are soft and clear, and the high frequencies are slender, smooth and full of airiness. The human voice is one of the great advantages of the tubes
- Unique and exclusive design patents: high-end, noble, luxurious, unique appearance. Its aircraft-grade aluminum alloy body is made of imported CNC carving. Its surface adopts high-end sandblasting process and oxidation process
- Two sets of output ports per channel: Pure copper gold-plated terminal blocks minimize transmission losses and restore the essence of sound. There are two sets of RCA outputs per channel, 4 RCA and 4 XLR (balanced). One channel can be connected to multiple power amplifiers to achieve sound crossing
- Two imported audiophile toroidal transformers: The X9 uses two imported toroidal transformers as the power supply, which is specially designed for electronic tubes. The power transformers are completely isolated from the circuit board. The transformers are treated with a high-strength shielding cover, combined with a high-frequency common-mode filter. They can avoid the magnetic field interference of the transformers, remove the ripple interference in the power supply, and provide a purer power supply system, so as to achieve no interference and no background noise. The background of the music is pure, and the sound is clean and natural
- Tubes imported from Russia: X9 adopts Russian high-end series tubes. They are of reliable quality and have a service life of 20-30 years. They have superior performance, high sound density, rich homophony, wide vocal range and wide sound field. The high frequencies are clear and layered, full of air, full and smooth, providing an immersive listening experience
- Original audiophile volume potentiometer for ALPS: The X9 uses a Japanese potentiometer as the volume potentiometer. It is reliable and durable, with low loss, high sound reproduction and accurate positioning. The damping feels smooth and the balance is consistent. It is a volume potentiometer used by many HIFI manufacturers around the world
- Input voltages can be switched
- The X9 supports vinyl record player input
- High-end all-aluminum CNC carved remote control: the remote control supports power on/off, audio source selection, volume adjustment and one-button mute
- Audiophile-grade selected materials create HIFI boutiques. Quality and effect go hand in hand.
  · German audiophile red capacitors for WMA and Japanese resistors for Panasonic are used. Their performance is stable and reliable.
  · The sound of high-end audiophile imported capacitors for Mundorf is silky and supple.
  ·  The original audiophile resistor for Panasonic is a special resistor for electron tubes. Its performance is stable and reliable.
  · German audiophile red capacitors for WMA: fast speed, low loss and natural balance of sound quality.
  · Schottky rectifier diodes: fast rectification speed, low loss and high efficiency. The power supply is smooth and clean.
  · Imported audiophile-grade filter capacitor is adopted. Good power supply is the foundation of good sound. The sound is dense, clean and clear, smooth and mellow.
  · Original MCAP NMKP for Mundorf: Original audiophile high-end electrodeless capacitors and audiophile capacitors for Mondorf are used
