He has a group of people using the Adnaco USB over Fiber Optical system. He is looking for tailor made a device which have the internal clock and wiring updated -  A USB over fiber optic device.  He is very keen on using a fiber optics to enhance the sounding on the USB device on DAC.  \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eThe design of Nocturnes USB Over Fiber Optics  \u003c\/em\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSo we decided to design them with audiophile's mind.
