Line characteristics
●Fully symmetrical X-Amp ultra-fast power amplifier circuit
●Fully DC coupled circuit
●Signal can be balanced or single-ended input
●High damping characteristics, can drive all low-sensitivity large speakers
●Strict sound: high resolution, first-class control, low frequency is even better
Design Materials
●Extremely large and thick chassis, 430mm wide, 430mm front and rear depth, 230mm high, including machine feet
●Two 600W Nippon Steel transformers, one for each of the left and right channels
●8 pieces of 10000uF audio electrolytic per channel
●The left and right channels are completely independent in design, and the amplification board, power board, and protection board are completely separated from the left and right.
●7 pairs per channel are precisely paired with genuine Japanese original Sanken tube king
●Ultra-large quiescent current, 300mA per tube
●Complete speaker protection, effectively protect your expensive speakers
●Equipped with soft start-up and power supply DC filtering functions
●Shute power socket and golden fuse
●Soundy high-quality terminals
●Acoustic RCA signal base
●Single crystal copper signal line for the entire machine
●Adopts American ALPHA solder wire
