Confused about adapter for RCA to BNC

I once had the opposite issue of yours, @stuartk . My transport had an RCA digital out, but the DAC I bought had a BNC in. The Dac did come with a male BNC to female RCA adapter and I am sure I must have used it initially (this was almost 30 years ago) but I did contact Canare Cable and they made up a digital cable that was RCA on one end and BNC on the other. Fast forward to a few years ago, I was having trouble with that cable (the DAC was intermittently unlocking from the transport) so I broke out he adapter that I mentioned but I noticed that the SQ was noticeably worse. I contacted Kimber and they made me up another RCA to BNC cable (I think it was D60) and that did restore the SQ. I was using that until a few years ago when I bought a new CDP.

Anyway, I did read that you resolved your issue for the time being, but just wanted to add my own experience with RCA/BNC adapters.

@stuartk great news! Hopefully the DAC meets your expectations!

@stuartk - I am glad you got it to work.  Enjoy the DAC.

I am surprised more equipment manufacturers do not use BNC connectors for digital cables.  To me, they seem to make a better connection than RCA.

I've been told both: that an adapter is bad and that it makes no difference. I'm getting a different one in a few days. It will be interesting to hear if they sound different. I'm not fundamentally opposed to getting my cable reterminated, BTW, if I decide to keep the dac.

Thanks. We'll see.

You could be right. I've never done a comparison.

@stuartk , I am certainly no expert on the subject.  There may be variables involved that have an effect on how one feels about it..  I remember when my old Canare  RCA to BNC cable started acting up I was feeling pretty proud of myself for knowing where I had put the adapter that the manufacturer of my DAC had provided.  I really wanted it to sound good, but it didn't, so that is why I wound up biting the bullet and buying another cable.  I suppose this may be one of those YMMV things.
