Original owner. Change in set-up necessitates sale. I used this Sonore OpticalRendu ROON lite as a ROON endpoint for my Nucleus Plus (also for sale; see other ad).  The Sonore OpticalRendu ROON lite is ROON ready and will only work with ROON as an endpoint. This bundle will allow you to optically isolate your ethernet connection. The 7V linear power supply is made in China and supplied by Sonore; it has a DC cable to connect to the OpticalRendu. Included are ethernet/Fiber media converter, two TP-Link SFPs, as well as, 1M optical cable as supplied originally by Sonore. The OpticalRendu Lite sounded great with the Nucleus Plus and is in excellent condition. Will ship only to US address. I will cover Paypal fee. Flat shipping charge: $25.00.
