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 analog sections.
Volume/Source/Sampling display using OLED has excellent visibility.
The 4mm thickness of the aluminum chassis to effective to blocks EMI/RFI interference.
The full-metal body realizes 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.
