River Cable Flexygy 8 Introduction

I know what you are thinking - not another speaker cable review?!? Don’t tell me some reviewer is about to take me on a tour of the wonders of exotic cables and how they magically can transform your hi-fi system into audio nirvana! Rest assured, we don’t suffer from audio nervosa (at least when it comes to cables) like many elitist audiophiles tend to. We are realists for the most part and do our best to keep things in perspective, especially on topics which are easily quantifiable through empirical data and analysis. Oddly it’s the topic of cables, one of the simplest components to analyze and quantify, that seems to be surrounded by the most propaganda and snake oil. We can only figure it must be because the differences between any reasonably competently designed speaker cables are so miniscule that some manufacturers must rely on these snake oils or newfound sciences to help bolster product appeal (directed towards unwary consumers who, through no fault of their own, simply don’t know any better.) Take a hobbyist for any particular passion (i.e. cars, fitness, etc) and plant the power of suggestion of them, sprinkle in some fancy techno babble while creating an urgency for the product, and they will likely buy it in droves. Add to the fact that audible preferences are very subjective in nature, and - wham - you got the winning receipt.

For a list of the common snake oils we have so far uncovered, I recommend reading the following article I authored titled "Top Ten Signs a Cable Vendor is Selling You Snake Oil"
