In Reply to: Perhaps because the frequency spectrum of a digital signal is less important than the cable's consisent impedance? posted by John Marks on March 22, 2014 at 06:49:34:
The fundamental function of a 75 ohm digital signal cable is not unlike that of a 75 ohm RF video cable. If folks keep that in mind, the difference between the requirements of a digital cable and a line-level analog cable may be better understood.
The most compelling reason to use a twisted pair or more complicated designs rather than a coaxial cable for analog applications is the ability for the cable to be unshielded, whereas a coaxial cable is shielded by nature. Many audiophiles find that shielding can do more harm than good for analog use.
However, there are coaxial cables that sound excellent when implemented as shielded analog interconnects rather than a shielded twisted pair, et al.
A new kid on the block is the new OCC copper version VH Audio Pulsar II coaxial cable for either digital or analog applications. I'm currently evaluating a stellar sounding DIY VH Audio Pulsar II OCC digital coaxial cable placed in my computer audio system. A new pair of VH Audio Pulsar II OCC analog interconnects are next in line on my DIY to-do list for potential use in my main audio system. I'll post a report sometime down the road.
