Стерео усилитель Audio-GD Master-3

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 (Total 1500W) core transformers 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.
