Balanced cables provide three benefits. You get locking connections in every case, and if you are running a significant distance you will have less signal loss than single ended, and better quieting capability as both poles are within each run. That's it. All other benefits are imaginary.
If your cables are only a meter or two, don't waste your money on the changeover. You might be able to imagine an improvement, but nothing will have changed.
