How much better is direct BNC vs adapter

Thank thank you both, for your responses. You have added to my belief that the adapter really isn’t hindering performance. I am curious to try a few different cables, I brought home a Cardas Clear, but the connector won’t go into the Node2. They have a little guard around the connection although I can use my Golden Ref’s on the analog outputs. And toolblue, I have plans to try the Acoustic Zen, recommended by The Cable Co, thru their lending library. 

Audioengr, if I understand you correctly, you are stating that BNC to BNC with an RCA to BNC adapter is better than a cable terminated as required? So the 75ohm properties of the signal are corrected by simply adding a second BNC connector? Just trying to learn.

I see now that there have been a couple posts favoring BNC to BNC and using a RCA to BNC adapter. So to echo facten’s question, why? I would like to learn the reason or logic as why this benefits the signal path more than a RCA to BNC terminated cable. Not arguing just learning.

Thank you, Steve
That helps me understand it better.
