True, I just threw in F because it's a very common A/V connection.

Originally Posted by syllabus /img/forum/go_quote.gif My coaxial cable made of pure silver and not even 75 ohm in impedance, terminated with RCAs on both ends and connected to my CDP through a RCA->BNC adapter, has a superior sound to a Blue Jeans Belden 1694A terminated with BNC to RCA (so without any adapter on the CD player side). Superior as in more detailed, with stronger and more firm bass. |

My idea is: silver is a superior conductor for digital signals, at least to the copper that is in the Belden cable. |

The fact that I found a non-75 ohm silver coaxial to sound better than a 75 ohm Belden coaxial, instead, is tangible fact. |
