Chances are your receiver is a few years old, which means you are probably not getting access to many of the latest technologies. Recent home audio/video systems comprised an AM/FM tuner, record turntable, cassette deck, and possibly a CD player. Some of these sources have nearly vanished -- they've been replaced by DVD/Blu-ray players, digital radio, DACs, HDTV sources, and portable personal media players.
By upgrading your home electronics, you will almost immediately realize incredible gains in both fidelity and convenience. The latest products make it possible to integrate many different elements of your electronic home, including entertainment, telecom, Internet, home security, and more.
