This Sticky Thread starts off with a really great summary of the concepts behind transmission of digital signals via cable by member, House de Kris. WARNING: This thread is intended as a technical reference (for learning) , and we reserve the right to edit the hell out of any post. No non-technical opinions, please? Meaning that this is not a place to compare cables, or to express your long-held belief that analog is better, or silver is better, or whatever. All such comments will be edited out. All comments amplifying, explaining, clarifying, questioning, or expanding on Kris' comments are very welcome, as are technical questions of all kinds. They're not only welcome, they're encouraged!
