@lalitk When I said work perfectly, I am talking about the sonics, the bit transfer is a given. My streaming is working in the fibre domain and everything before the Rendu does not matter from my experience with the other 2 OpticalRendu's I have. I initially had concerns about the quality of the switches but not anymore. My first Ubiquiti switch sells for $400-$600 now (I paid $150 before it became popular). My second switch was $75 and the 3rd one $45. I am not spending money on switches anymore based on my experiennce.
I also used to own the Lumin X1 and used a direct fibre into the X1 DAC and compared that with the OpticalRendu into the X1 and other DACs.
Very interesting test results. I ended up with 3 OpticalRendu's. The X1 was also a great streamer. As was a PlayBack Designs Stream-IF I had in the house (tested with SPDIF not the available PLINK fibre).
