The core technology of the amplification part is the development and development of a cholelithiasis hybrid DC amplification circuit to accumulate years of experience, allowing you to experience the unique sound quality and color charm of the cholelithiasis hybrid front-end amplifier.
Adopting a dual mono fully balanced amplification circuit design, the two channels are completely independent. To reduce dynamic crosstalk interference, each channel is operated independently using a power transformer.
Six fever grade electronic tubes and matching gold-plated tube holders ensure excellent sound and quality performance
Electronic tube Class A output buffer with up to 30V undistorted output voltage, easy to match and drive numerous post stage power amplifiers.
The volume Potentiometer is a large ALPS quad high-precision Potentiometer made in Japan, which has small channel error, long life and ensures beautiful voice performance. Added remote control volume system, making users feel more convenient
A large number of advanced audio components are used inside the machine, such as the use of German Mcap brand oil immersed capacitors, WIMA brand MKP audio dedicated thin film infinite capacitors, 1% high-precision metal film resistors, and precision high-voltage stabilized power supply, to achieve high-quality sound quality and color.
Imbalance uses gold plated advanced RCA terminal products, and balance terminals use Swiss NEUTRIK brand products to achieve more ideal transmission of audio signals.
The AC power input socket adopts Japanese FURUTECH brand gold-plated products, and the safety tube uses Swiss SCHURTER audio dedicated advanced safety tube to ensure high-quality demonstration.
This machine has fiber optic, coaxial, and USB digital input terminals. USB uses the American "XMOS" solution, and the decoding chip uses the ES9038Q2M chip.
