The materials used for CD-MU8 are quite particular, and the decoding chip adopts dual ES9038Q2M. The resolution of this chip is quite good. The op amp also uses high-quality OPA2604 (the price of this op amp has nearly doubled), which is significantly better than LME49720, OPA2134 and other op amps. The capacitors used Nikon's green MUSE, gold-letter KG, gold-letter KZ, MUSE and other capacitors. In addition, the high-frequency transparency, low-frequency dive, and mid-frequency fullness have all been well performed, which can be achieved by non-ordinary industrial capacitors. The amplifying output stage adopts the Soviet 6H3 tall tube, which makes the machine more attractive, more durable, and can let you indulge in music.
