Sony STR-DE545 Amplifer 7x 100W per channel, with remote, lots of settings. will run 4x fronts, 2 rears, sub & centre speaker (which I am also selling). The remote will also control a Sony TV & DVD player (which I also have). Google the model of the amp for a review... Has a scratch on the front of it which is shown in the pictures.
