Functions and features:
1. Using high-quality triode 300B as audio front-end amplification and electronic tube rectification, combined with power transformer, output transformer and independent transformer developed for many years, it shows an extraordinary sense of music. The sound field is fresh, dynamic and strong, the notes are smooth and the positioning is clear.
2. The headphone jack has two sets of outputs, which can be connected to two headphones at the same time.
3. There are five impedance outputs, providing users with more choices.
4. High quality component materials are adopted to ensure good working stability and high fidelity timbre.
a. All aluminum alloy case is carved by CNC machine tool, which is solemn and elegant and has a good shielding effect.
b. The volume potentiometer adopts high-end step-by-step balanced amplification without mechanical noise.
c. Swiss Neutrik high-end gold-plated earphone socket and pure copper selection switch are specially selected to ensure that fatigue contact noise will not be generated after long-term use.
d. High quality input and output terminals ensure long-lasting good contact performance.
5. And class a combined power amplifier, which provides users with high-quality amplifier with driving sensitivity of 88DB,
HiFi speaker with power of about 100W.
