Master-3 （2019 Edit） - Power Amp#

Master-3 （2015 Edit） is fullu balanced design with ACSS technology. The users MASTER-3 can enjoy the sound of music that was given by musicians, sound engineers and music producers, devoid of hardware coloration. The elegant simplicity of the MASTER-3 resulted in a shortening of the signal amplification. process. MASTER-3 amplifies the signal in only one step, which greatly limits the distortion characteristic of the conventional design based on OPA. The effect of this has become a high dynamics, detail and "referentiality" of the sound reproduction. Devices of Master series can be used successfully in professional applications.

• Fully balanced design, the gain stages and pre-driver stages work in class A, built with discrete analog stages without any OPA or coupling caps in the signal channels.
  
• The output transistor stages work in high idle current state . The Diamond Cross output stage design avoids "switch distortion" as well as class A amps.
  
• Non- feedback ACSS analog amps.
  
• 2 analog inputs: XLR / ACSS
  
• Applies 24 pieces of ON Semiconductor “the King of transistors” MJL4281/4302. Supports 250W X2 (8 Ohms) output.
  
• The capacitance of the whole machine reaches as high as 140,000 uF, with two 750W circle core and two R cores transformers (Total 1500W) and separate power supplies for the right channel and left channels.
  
• A total of 4 groups of high-quality class A parallel connection PSU's supply the gain stages.
  
• Applies all audiophile grade components, including DALE resistors, WIMA caps, custom order NOVER (UK brand) caps, all audiophile grade input & output sockets and gold IEC socket. Applies the round-corner style chassis which has lower syntony or vibration. Between the transformers and signal amps resides a thick metal plate to avoid interference.
