  • Pure tube circuit design, the preamplification part uses 2PCS 6N8P(6SN7) and 2PCS 6N9P(6SL7) tubes, and the power output uses 4PCS PSVANE 300B tubes. The charming tube sound is sweet and warm, full and mellow.
  • High-quality materials are used to ensure excellent performance and long time stable work, such as EI114 power transformer(made of Japan silicon steel sheet), EI96(Japan Z11) output transformer, EI 57 filter inductor, RUBYCON or NICHICON large filter electrolytic capacitor, customized MKP audio capacitors, and high-end gold-plated RCA terminals and speaker sockets etc.
