Your chips are using are not buffer chips, so they cannot be used as such. This is a chip commonly used for headphones: http://focus.ti.com/docs/prod/folders/print/buf634.html
Opamps have tons of different uses, the circuit you posted is a voltage amplifier.

Does a voltage amplifier function properly as a pre-amp? The site I pulled the schematic from said that this was for amplifying audio.
