Unless you wish to build a DIY digital cable or video cable, there is no benefit in using a 75 ohm friendly rca connector. In fact, the notion of a "true" 75 ohm rca connector is kind of an oxymoron. BNC is a more ideal if not a proper 75 ohm connector. However, a number of rca connector designs can function very well if terminated properly for a DIY 75 ohm digital cable project. That way you can choose good sounding rca connectors in their own right as well as maintain the proper 75 ohm characteristic impedance of a coaxial cable. Maintaining the 75 ohm characteristic impedance of a coaxial cable avoids digital cable reflections caused by an improper termination method that *deforms the shape* thus relationship of the dielectric positioned between the center conductor and the braided shield. The shape of the dielectric needs to be consistent (not compressed) along the entire length and to the very ends of a 75 ohm coaxial cable, right up to the connector termination point. In a nutshell, don't squash the ends of a 75 ohm coaxial cable unless you don't care about digital cable reflections...
