Got this Amp - TOA BG-1120 MIX/AMP, brand new in box, it appears that its meant for an office or more of a background/foreground music as description states. Im new to audio systems but i'm trying to assmble a nice home stereo system. Getting Onkyo TX-SR705 receiver, got onkyos fm tuner, and cd changer as well. Haven't decided on the speakers yet, but really wondering if this amp worth using for a home system, and is it good to power anything. Is there a point in keeping it and are there any more useful alternatives ? Thanks
