I would also recommend Nsgarch's reply. Spending a bit up front and getting a comparison and how a given cable reacts in your system is by far the best approach. It does take more time up front, however you are allowing yourself at least somewhat of an educated decision between a few options as to which you prefer. Also, after you chose one cable and decide what you like, you can call the Cable Company and describe what you liked, and what else you wish it had (if it didn't do something right) - they will then point you in another direction that is normally very sound advice. They also usually have most of the cables previously owned to send out to try. Good luck on the search.
