Coax to BNC connection for digital


I one has a DAC with unused BNC input and a streamer with coax output, can a cable be made with appropriate terminations that would not sacrifice sonics?

I use the DH labs d750 which is terminated with rca on the transport end and bnc on the dac end.  No adapter necessary.   It is an excellent cable imho.

Thanks all for the this information. You have answered mine main concerns, regarding having a cable made, if there were adapters, and the issue as to 50 vs. 75 ohms service. I do have 75 ohm RCA cables and will will most likely look for an adapter. 

Given the DAC has BNC, should I purchase a server with BNC output I would  then just purchase a BNC cable which I suppose would need be rated for 50ohms.

Hi Mesch,

The output impedance of the server, the input impedance of the DAC, and the impedance of the cable should all be the same, or there may be adverse sonic consequences that are equipment and cable-dependent, and that are essentially unpredictable.  BNC outputs, inputs, and cables used in digital audio applications are often 75 ohms, but are 50 ohms in some cases.  It would definitely not be good practice to connect a 50 ohm output to a 75 ohm input, or vice versa, although in some circumstances doing so **might** happen to provide reasonably good results.
