Analog Cables for Digital?
Atul Kanagat -- Tue, 02/17/2009 - 13:55
I have been using regular interconnects routinely when I can't put my hands on a 75 ohm digital cable. Does it matter? What are the pro's and con's of doing this?

Ideally, a digital cable will be part of a 75-ohm transmission line, terminated with BNC connectors. Because most consumer gear uses RCA connectors (which are not 75 ohm), the connection system is compromised to start with. Nonetheless, cables engineered for digital data tranmission are usually preferable to interconnects designed for analog signals. I have, however, found some analog interconnects that work very well for carrying digital signals (AudioQuest Diamond, for example). I think that this is just by chance. If an analog interconnect sounds good in your system when used to carry digital data, there's no reason not to use it.
