This is for those looking to build their audio system in a living room or “family room” environment. Or, maybe your wireless router is in a different room than where your home theater system is located. While getting through those walls with a wired connection is nowhere near as simple, once you do, you have fidelity. With a wired connection, you simplify connectivity, often making problems easier to diagnose. While a wired system may be more of an up-front investment, ultimately, it should last longer than most wireless surround systems.
