There is a lot of information in the threads on this site. I entered "Morrow Audio Speaker Cables" in the forum search and there are over 500 posts you can check out. You can sort them by relevance or date.
You can also read about their design technology on their website. My personal experience is that speaker cables made from individually insulated solid core wire sound best to me. Here is what Morrow says:
Morrow Audio signal cables use ONLY solid core OFC (oxygen free copper) wire, NEVER stranded. Our cables contain multiple runs of wire. They are mono strands, individually insulated from each other.
