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

Audio Engineer who participates in these forums sells a $275 BNC cable with RCA adaptors.  I purchased one a few months ago.  Beats the pants off RCA coax cables I have tried for twice the price.

Don't do BNC-RCA cable.  Use the BNC-BNC cable with a 75 ohm adapter, not 50 ohms.  For 99.9% of systems you will not hear any degradation with the adapter. You can get them at Markertek.com

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.

The way I understand it - and Audioengr please correct me if needed - that a natively BNC terminated digital cable, 75ohm, with an adapter for RCA, is better than a natively RCA terminated cable, 50ohm, with an adapter for BNC connections.
