Next generation digital circuit design:
The D-05u supports high-grade CD/SACD reproduction as a matter of course but additionally can support the reproduction of file sound sources of up to 192 kHz/32-bit PCM data and DSD data (2.82 MHz, 5.64 MHz) by connecting to a PC or Mac via USB cable. The jitter of USB signals is completely eliminated by the dedicated DSP via asynchronous communication, whilst the jitter of CD or S/PDIF signals is eliminated by the embedded DAIR high-precision clock. A dedicated jitter reduction chip eliminates jitter from SACD signals. In addition, the D-05u features a low phase noise clock module that reduces noise near the oscillating frequency and therefore improves the accuracy of the entire signal transmission.

Fully balanced analog output:
In order to achieve the precise musical expression required from the uppermost of the integrated system such as the D-05u, the accuracy of the proprietary LxDTM mechanism combined with cutting edge digital technology is necessary. The design of the D-05u ensures that signals read by the LxDTM are sophisticatedly digitized into analog signals through a high-precision converter and then output through a high grade analog amplification circuit.The D-05u has achieved a reduction in the impedance of the differential output of the D/A converter, PCM1795, operated at the monaural mode with the use of a high sound quality buffer circuit with fully balanced configuration (identically configured amplifier x 4 units). This unit enables next stage components such as an integrated amplifier or a control amplifier to be powerfully driven by the D-05u.
