This machine design refers to the circuit design of Marantz 7, each sound channel with a 12AX7 for voltage amplification, DAN1 is connected to the cathode follower as a signal buffer, its role is equivalent to using the transmitter, so you can have a relatively low output internal resistance, its circuit characteristics is the overall loop feedback design, This is a major factor in Marantz7's fame.

After several revisions, the shop successfully launched the finished product machine, the sound quality is amazing! The friend that likes human voice and gallbladder flavour might as well try, treble is exquisite and not harsh, medium tone is warm alcohol, bass is loose and do not owe strength to be able to expect effect intentionally!

Voice, natural, delicate, string string smooth, stretch, listen to more love to listen to, the sound field is very atmospheric!
