State-of-the-Art Digital Processor — Innovative MDSD (Multiple Double Speed DSD) digital processing circuitry with double-speed high-precision moving-average filter circuit configuration for straight D/A conversion of DSD signal. Support for playback of high-resolution sources in 5.6448 MHz (1-bit 2-channel DSD) and 384 kHz (32-bit 2-channel PCM) format. Six digital inputs including HS-LINK and USB. Informative readout shows sampling frequency and number of quantization bits of input source, based on actual measurement.
■ Ample clean power is provided by separate power supplies for the digital and analog sections, each with a dedicated power transformer and large filtering capacitors.
■Ultra-high-speed FPGA (Field Programmable Gate Array) harnesses digital processing power to implement innovative MDSD reproduction with double-speed high-precision moving-average filter circuit.
■MDS++ type D/A converter with eight circuits driven in parallel.
One 32-bit HyperstreamTM DAC chip (ES9018 from ESS Technology Inc.) is used per channel, each comprising eight circuits driven in parallel. This improves overall performance by a factor of about 3 as compared to a single converter circuit, thereby achieving outstanding low-distortion results.
■Direct Balanced Filter uses high-precision op-amps and performs totally separate analog filtering for line and balanced signal paths, to prevent any risk of interference when both are used simultaneously.
Six digital inputs: HS-LINK, coaxial (2), optical (2), USB.
Line and balanced analog outputs (1 each). Phase selector switch for balanced output.
