How much better is direct BNC vs adapter


Just got my new Chord CuTest and it uses BNC coax and my Bluesound Node2 uses RCA. So I am currently using a RCA to BNC adapter with. Kimber AGDL RCA/RCA cable. I am considering buying a new cable and have it terminated RCA/BNC, but wanted some opinions from fellow Audio-goners, is it worth any further concern  to eliminate the adapter. 
2nd part to this question, is what cable under 500.00 would you pick?

Thank you in advance

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.
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?

I have explained this many times on this forum.  RCA connectors cannot be properly terminated to coax cable, I don't care what RCA you use.  Coax cables have BNC connectors specifically designed for each type, so that the impedance discontinuity is minimized.  Using RCA terminated to a coax will cause unwanted reflections, resulting in jitter at the receiving device.  Adding a BNC to RCA adapter is usually harmless and does not result in compromised SQ.
