So after coming up on some infinity speakers, my local thrift shop had this "Synthesizing Reciever". I need one to operate my speakers so I picked it up. It works and has a built in tuner (good for space-sake). They hit me $30.00 but I can't even google any decent information on it. Any help? Is it worth the cash or should I hold out?

I only have until Aug 14 to return them so ANY/EVERYTHING constructive is welcome

Thanks

***I wasn't sure if this fell under "Amps"
