Hi-end Class A integrated amplifier

Balanced Amplifying Circuit
It adopts symmetrical, balanced, differential circuit and the sound is transmitted through BTL output configuration. This circuit helps to bring better sound with lower distortion and more purity.

Long Term Pursue
30+ years pursue in AD series amplifier

New version, new chips
DSD digital decoding
ES9038 chip offers up to 22MHz signal lossless decoding and Hi-Fi sound.

 
Balanced Input
XLR audio ports
Less interference
Low distortion

Phono port, classic appreciation.
It supports MM/MC cartridges for easy compatibility.
The rich sound will take you back to the classic time.

Subwoofer Output
XLR/ RCA output ports connected to an active
subwoofer will truly meet the taste of bass fans. 

Bi-wiring Connection
It supports standard connection and bi-wiring connection modes. When it's in the bi-wiring connection mode, treble and mid-bass are separately connected with the amplifier so as to reduce interference and improve sound effect.
 

Class A/ AB/ AUTO Modes
It has three built-in circuit modes: Class A, Class AB and auto-switch between Class A & AB, which is one of the symbols of our high-end Hi-Fi amplifier. Use the remote control to achieve one-click switch among these modes.

High power & one-click switch
200W for each channel to drive most famous speakers. Use the remote control to achieve one-click switch between integration mode and purely amplifier mode.

Decoding Chip ES9038
This chip enables it to decode multiple audio formats.
DSD decoding: DSD512, 256, 128, 64
PCM sample rate: 32bit/768kHz
Dynamic range: 129dB
Distortion: -120dB

High Sample Rate for High Quality Recording
 

Operational Amplifier
It adopts 9 OPA1656 optional amplifiers form Texas Instrumnets to form full balance amplification, bringing analytical and warm sound.

2 way optical inputs, 1 way coaxial input
and DSD lossless decoding.

High Power Transistor
A total of 24 Toshiba transistors 1941/5198 for bright treble, bloat mid-range and sonorous bass. 

Volume Controller Chip
It adopts NJW 1195A volume controller chip with -118dB low noise and 0.5dB adjustment step. Lower distortion and better channel separation.

High Capacitance
A total of 16 capacitors to offer 128,800μF 
capacitance for powerful driving.

High Power Transformer
860W toroidal transformer for strong power driving.

Wide Voltage Design
As an amplifier specially designed for audio users worldwide, it adopts its patented wide voltage design handling AC 110V and AC 220V.  
 

Multi-chamber Layout
The areas of input, power storage, power supply
and amplifying are separated into chambers so as
to reduce the interference
of free electromagnetic wave.
