SOtM dX-USB-HD Audiophile Asynchronous USB Interface for 24/192 Playback:
(AES/EBU, SPDIF Toslink, SPDIF RCA Outputs w/Optional External Power Input)

The SOtM dX-USB-HD is an audiophile asynchronous USB interface for 24/192 playback. This interface includes AES/EBU, SPDIF Toslink and SPDIF RCA ouputs  to insure compatibility with your DAC of choice. This interface automatically switch's between USB power and external power should you decide to audition with an external power source. The external power source can be a battery or a linear supply. When using USB power the interface has a unique design incorporating an ultra low noise regulator circuit. This interface also has dual full size high quality oscillators.
