Adapters for RCA

I have an Audio Research DAC and transport. I am currently using coax digital cable and wish to upgrade, but the better cables all seem to be RCA or AES/EBU. My equipment has no RCA jacks. Does anyone know of adapters that will permit RCA plugs to be used?
what kinda terminations does your equipment accept? all the digital coax ic's i've ever used have male rca's attached to both ends. aes/ebu ic's require balanced inputs/outputs. boulder makes an aes/ebu>rca adapter (there are no rca terminals on their dac/pre or separate dac) but i'm not certain they would work on your stuff.

BTW, if you don't like my post, just buzz by it. it ought not be necesssary, however, to point out that i have as much right as you to use my keyboard as i see fit. -cfb
Like CFB stated, in DAC/CD a single RCA output/input=coax.
What connectors do you have? AFAIK, Audio Research used RCA or BNC coax, XLR (AES/EBU) and an optical connector. I doubt that they have no RCA connectors unless this is a strange variant.

BTW, the coax you are using must have RCA or BNC connectors which is used by many cable manufacturers.
I assume you are using a BNC coax cable. These are in many ways better than RCA coax cables (both are used to transmit identical 75 ohm s/pdif signals, but BNC is a better shielded connector). While RCA digital cables are more common ALL of the better digital cables should be available in BNC vrsions. Do not go to RCA if you don't have to. Great digital companies like Muse don't have any RCA connectors, just BNC or XLR (and their fancy I3W).
