I would recommend a 5.1 channel setup for your main home theater, sound bars are OK for a bedroom setup IMO.
This Onkyo receiver with Dirac has enough channels for a 5.2.4 system and is on sale. ($899)
and a JBL 550P sub
The JBL 5 series is a part of their upper end Synthesis line and are now on sale at substantial discounts, especially the sub.
You cam always add additional speakers for height channels/atmos later.
