After spending a few Benjamins on a high-end stereo system, casual consumers are content with using the audio cables that come in the box. Don’t settle for less. Since these interconnecting wires are actually the most important components in your setup, do yourself a favor and look into HDMI cables. The benefit of using these over analog cables is improved digital transmission, plus they manage compressed audio better. You’ll also notice a boost in sonic output when watching Blu-Ray discs.
