Ocean D/A

A great deal of effort went into the design and construction of this “emotional” device, the Ocean DAC. It is built with the highest precision, taking into account every little detail. The "Listen, Design, Listen again" design process and our special technology (e. g. “Asynchronous Data” and "Isolated D/A Power System") allow us to produce Ocean DAC with truly rich natural sound, creating an unimaginable musical experience.


Used properly, it will give you many years of enjoyment.

Asynchronous Data technology


In fact any PLL (phase locked loop) cannot be ideal. The noise from power supply or grounding, changing of temperature, and the jitter from input clock all have negative impacts on the performance of PLL. That’s why most DACs are highly dependent on the quality of the digital signal they are fed.






However, the OCEAN DAC delivers outstanding performance with even less-than-ideal digital signals.


It uses the “Asynchronous Data technology”, an “Asynchronous Data Buffer” can provide a steady, consistent source of digital data to the DAC core which are responsible for changing that data into music. Even if there is significant “jitter” (inconsistencies in timing) in the incoming digital information, the output of the “Asynchronous Data” is controlled by a special clock which tremendous accuracy. The result largely eliminates the jitter and allows the musical information to be reproduced cleanly, without jitter-induced distortions.





Isolated Digital/Analog System


It is a fact of life that digital circuitry is so noisy. Saturating logic, such as TTL and CMOS, draws large, fast current spikes from its supply during switching. However, analog circuitry is quite vulnerable to noise—on both power supply rails and input signals. The noise on input signals will inevitably couple into the inside analog circuits through the stray capacitance, CSTRAY. Maintaining a wide dynamic range of analog circuitry with high SNR and ultra-low THD in a hostile digital environment is a real problem in a DAC design.




So it is sensible to use "Isolated Digital/Analog System" technology, which can eliminate noises and prevent digital noise from reducing analog performance. A separated Digital/Analog System is used in our DACs to reduce analog output distortions to a minimum. Ocean DAC makes truly rich natural and stirring sounds, which you never have experienced through your system before.
