Almost all network amps are DLNA based, so you can stream audio from your PC / Mac if you enable DLNA via software on your computer. The ability to handle different audio specs / formats will differ brand to brand. If your phone/tablet has a DLNA server app. then you'll be able to stream from this... sometimes it's built into the amp manufacturers own app., other times you may need a 3rd party app. Some receivers also have Spotify / Pandora / Airplay support built in.
