What would be the reason to use this? Is the sound better than the RCA jacks on back?
Single-ended digital audio cables are supposed to be 75ohm. BNC is supposed to be a true 75ohm cable vs RCA, where it is and sometimes it isn't a 75ohm cable(depends on who you ask...lol). That's what you want in both the composite video and digital audio cable. It's supposed to be what they say it is, a 75ohm cable....just remember that.
Now....
Stereovox HDXV or their new cable, XV2, is a digital audio cable but it can also be used as a video cable.
The advantage of it is that it has excellent connectors and it is a good cable for the money.
The purpose of this cable is:
1.
As a digital audio cable from transport to DAC.
If both the transport and the dac have RCA digital out, you would use it with its RCAs in place.
2.
If one of the components has BNC and another has RCA, you can take the RCA off on one end and it becomes a BNC to RCA. In this configuration, in your particular scenario, YOU would utilize it as a component video cable RCA-to-BNC, or BNC-to-RCA, whichever way you want to call it, but you would need 3 of these cables.
3.
RCAs come off on both ends of the Stereovox cable, so you can also have it as BNC-to-BNC.
The connectors are very, very solid and they are nothing like the adapters you bought from radioshack.
Just research this a little further, make sure you clearly understand what you need and what you're trying to achieve.

You can also give them a call and explain your particular set up to make sure this cable is what you need, but as far as I understand, I think this is it.
