Question about Sony Str-Dn1080

The speaker terminals where one can connect Dolby Atmos speakers are very flexible (see pp 21 to 25 of the Manual). On the back of the Amp, against these terminals it reads: Surround Back / Height /Front Bi-amp / Zone. So you can definitely connect "normal" speakers to these terminals. (I use them to connect to the treble terminals of B&W floor-standing speakers, bi-amping.) Whether normal speakers will sound like Dolby Atmos speakers, I am not sure. It is possible that in the set up process, you may be able to change the natural sound of the normal speakers, as the Amp will change the sound of speakers to match the set-up that you want.
