model S504 "unison"
16 bit Non-Oversampling DAC
Non-oversampling D/A converter and the power supply unit is built in a compact size. It is characterized by sound quality with highly pure musical power. There are 4 variations for each interface, COAXIAL (S/PDIF), USB (PC), OPTICAL (TOSLINK) and I2S. In addition to the current-mode output, you can connect directly with the conventional voltage-mode amplifier with this single model.
Smart Size ― Easy to wiring from rear panel.
In size-held (100×200mm) in one hand, you do not choose a place to put it. Since the depth is narrow, it does not get in the way routing of the wiring from the rear panel.
Japanese Taste ― The texture of Japan.
Elegant and cool, finished with a timeless design. The color of the handmade Japanese paper is by hope, you can choose from below color variations. You can also choose gray-smoke monotone or clear-transparent panel without Japanese paper.
Simple Front Panel ― Easy to operate.
We designed as soon as possible to immerse into the music by losing cumbersome switches as much as possible, just plugging in the cable and turning on the power.
