Master-3 BALANCED POWER AMPLIFIER

Master 3 power amplifier is designed without any compromises using the best components on the market! Like all products of Audio-GD the amplifier is entirely made by hand and for a reasonable price. The analogue amplifier stages of this amplifier are non-feedback and DC coupled without any opamps, all discrete. The power supplies of this amplifier are feeded by 4 transformers, 2 per channel and RCORE for preamp sections. Audio-GD uses a technique that is quite unique in this price range, and designed using "Diamond Cross output stages". This integrated amplifier is a real balanced ACSS solution and delivers 250W per channel @ 8 Ohm and 500W per channel @ 4 Ohm speakers. No wonder this magic piece of analogue amplifier sounds incredible good: Neutral, detailed, very good 3D staging and authority.  


SUMMARY
  • True Balanced ACSS Integrated Power Amp
  • Fully balanced design, the gain stages and pre-driver stages working on class A , built by 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 well as class A amps.
  • Non- feedback ACSS analogue design
  • Installed 24 pieces transistors: "the King of transistors MJL4281/4302"
  • Supports 250W X2 (8 Ohm) output & 500W x2 (4 Ohm).
  • 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)
  • Completely separated design, separated power supplies for the right and left channels.
  • In total 4 groups of high-quality class A parallel PSU's to power gain stages. To achieve a high S/N, the control circuit is powered with separate regulators.
  • Audiophile grade components, including DALE resistors, WIMA caps, custom order NOVER (UK brand) caps, all audiophile grade input & output sockets and gold IEC socket. 

 


 INPUTS
  • XLR

  • ACSS (XLR 4-PIN)


OUTPUTS
  • 2 x Speaker (LEFT & RIGHT) Neutrik output IEC sockets.


ACSS TECHNOLOGY

MASTER 3 is a discrete design applying the latest ACSS technology which improves the XLR connections to be able to sound as good as the ACSS connections. It seems complex, but in fact it is most straightforward design in the world. There are a lot components in the power supply providing rich and clean sound. The

MASER  3 power amp has a single “voltage" gain stage to process signals, but works fully in ACSS mode; which in fact is a current gain stage instead of the standard voltage gain stage. The voltage gain state applied by almost all manufacturers requires at least two or three voltage gain stages. We implemented most elementary and shortest signal journey resulting most neutral and cleanest sound. MASTER 3 applies ultra-low distortion single stage ACSS amplifier soldered directly on the motherboard to reduce noise floor even more. The gain stages and pre-buffer stages are all designed to work in pure class A .The diamond cross output stage design avoid "switch distortion" as good as the best class A amp.The ACSS is a non-feedback technology is designed with discrete amplifiers.

Most people think the feedback design offer better specs in test measurements, and non-feedback isn’t as good. Putting the measurements aside, non-feedback offers more pleasant sound for the human's ears. This is a pyridoxal conflict of classic circuits. Our developed ACSS named technology opens a new field: It can offer a neutral sound with very low distortion and high linearity. Retain the dynamics, detail and neutral sound without sounding bright or harsh.

All signal gain are in current mode, achieved by the unique, superb open-loop multiple output current mirror. Incomparably precise and ultra-low distortion in the gain signal is the result. The signal path is balanced throughout and all transistors work in class A mode.
