I have owned and liked Onkyo,
However
This unit does NOT have front preamp out, which is needed to someday setup a separate amp (with pass thru) for the front speakers. The AVR still controls the front volume along with the other channel's volume
Denon's and Marantz usually have front pre-out, (not every model)
I find Crutchfield a good source of info,

look at the rear view, find pre-out, many only have SUB, some have zone 2 and/or zone 3, not front pre-out
