High Quality Digital Coax RCA to BNC Adaptors


Anyone know of any high quality RCA to BNC adaptors? Does using an adaptor degrade the digital signal quality? Would it be better to get my MIT Oracle digital coax reterminated rather than use an adaptor?

If possible replace your chassis RCAs with 75 ohm BNCs and use fully BNC cables.
Another vote for Blue Jeans Cable. I have a few of their Belden 1694A with Canare BNC on one end and RCA on the other that I use depending on the "configuration of the week" of my system :)
