Looking to upgrade from my 4 channel surround sound.

Will feed audio from flat screen via optical link if possible but also want to connect cd player & cassette deck via standard RCA connections.

What is the difference between 5.1 and 7.1 ?? The number of speakers ???

Needs AM/FM tuner as well.

Under 500 bux for a price range.

Thanks in advance.
