Full Balanced AMP Circuit, Lower Interference from Sound Channels or PCB Pole

After adopting CS4398 and full balanced LPF, which is much better than single end LPF, not only do the THD+D lower to be 0.00067%, but also isolation is developed with more details. All signals from decoder modules are optimized through using OPA2604, which is one operational amplifier IC with good performance on output HIFI sound.

Flagship DA Processing, Power System

A280 consists of leading ultra-low noise, class A chip, dual shield, damping embedment transformer and full-line stable voltage system, ensuring best power performance and develop the sound to be more reality, flexibly.

Professional Discrete Headphone AMP

Deep optimized from A200, A280’s AMP adopts discrete current & high-voltage circuit, with ultra-low internal impedance. The driving power is more than 5W with several times higher instant output power, which could guarantee the perfect performance of driving 32~600 headphones, like K701, HD600, HD650, T90, T1, HD800, K812.

Abundant Interfaces, Deluxe Materials

Used as independent digital audio transform system or independent DAC&AMP, this is easy to match with other style audio systems. Besides 6.35mm AMP, USB input, network and SD card interface, optical & coaxial digital input & output interfaces and full balanced single-end analog output are designed for A280. All interfaces are made of high-end gold-plating material, power socket of pure copper, with customer designed chilled alloy fuse in it.

Support CD Ripper and Playback

After connected with CD-ONE, A280 supports function of CD ripping and play precise streaming data.

Elegant Appearance, matched with Deluxe Furnishings well

The case is made of aluminum CNC handled material, while the front panel could change to be silver or gray along with different light.

Stable DLNA Network Control and More Function

A280 could be remote controlled by APP software installed in M.B., PAD and computer through network, while album information shown synchronously obtained from internet. The management of folders, music lists or search function could also be easy to proceed.

More play Modes for You

SD card, USB flash disk, different style hard disks, NAS and others are supported ideally. NAS hard-disk cartridge is the first recommended mode, which is very easy, functional with perfect sound playback.

Abundant Functions

Not only professional high impedance headphones could be pushed, but also different AMP or loudspeaker boxes can be matched with A280.

A280 has three versions:

I (no headphone AMP) $1106

II (no digital input) $1237

III (full version) $1293
