Hi @carbonero, I connect my RS130 in USB to my MSB Diamond V. Tried several hi-end (i.e expensive…) USB cables and far better results are through ROSE’s RS720 Optical fiber cable from RS130, and small (20 cm) USB cable from RS720 to my DAC : very good solution at reasonnable price !
This DAC has no ProISL option, like in my previous MSB Discrete, which I didn’t try at the time, since I didn’t have the RS130/RS720. In any case, I believe that it could be the utltimate best solution, to connect directly the RS130 USB fiber output to the ProISL input, taking advantage of the modular approach of SFP coupler into the RS130, allowing you to select a compatible fiber with the ProISL… avoiding ANY USB cable !
Please kindly keep us posted here : mostly interested to know if you try it and how it works !
