Real Balanced ACSS Mono Power Amp
Supports XLR and ACSS input
80 pcs output transistors
What's new in the Master 2H:
The Master 2H applied the newest output drive stage design, which is same as the HE-2 . The Master 2H had assemble 80 pcs ON Semiconductor transistors, larger power transformers and the caps, boost the drive ability achieve the monster level . The newest output drive stage design had the ultra low distortion , low to -120DB even with the normal listen volume , keep the sound quality had more transparency, clean, less coloration and dynamic .
Fully balanced design, the gain stages and pre-driver stages work in class A and are built with discrete analog stages without any OPA or coupling caps in the signal channels.
The output transistors stages work in high idle current state . The Diamond Cross output stage design avoids "switch distortion" as good as class A amps.
2 group analog inputs: XLR / ACSS
Applies 80 pcs ON Semiconductor transistors. Supports 250W X2 (8 Ohms) output.
The capacitance of the whole machine reaches as high as 260,000 uF, Two 800W (Total 6000W) core transformers and two R core transformers , Separate power supplies for the right 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 board to avoid disturbance.
