    Comments about Pioneer VSX-523-K 5.1-Channel AV Receiver:

    We use this at my church with a 4 zone splitter to send music from my iPod to four different areas. It's plenty powerful enough to send music throughout the hallways, offices, chapel, and gym at background music volume levels. Or, you can crank it up louder for a party. It can control your iPod with the included remote.
