Features

High quality toroidal power transformer

High-performance DAC-ESS ES9026PRO.

USB DAC: PCM 32 Bit/384kHz and DSD DSD64 (DoP)/DSD128 (DoP) DSD64/DSD128/DSD256 (ASIO Native).

COAXIAL/OPTICAL DAC: PCM 24 Bit/192kHz and DSD DSD64 (DoP).

Placed balanced/unbalanced headphone output: max output power 2000mW + 2000mW @ 32ohms.

Placed RCA/XLR input/output interface: could be a Preamplifier.

Volume control system: 128 step attenuator. Accurate control volume to achieve left/right channel balanced.

Isolation circuit: completely separates the grounding of the digital and analogue sections.

Volume/Source/Sampling display using OLED has excellent visibility.

The 4mm thickness of the aluminium chassis to effective to blocks EMI/RFI interference.

The full-metal body realises both vibration control and elegant style in an A4-size body that enables placement on a desktop to be a PC HIFI system or to be a small stereo system.
