Recently bought the LSIM 707 pair and the 706c + a pair of 703.

Also bought Sony STRDN1080 7.2 Channel Atmos Network AV Receiver. Will it be enough? I've read that we need an external amp to power up those speakers. Is that absolutely needed? Also, would you recommend adding a sub? I live in a condo so I won't really crank that up I just want the most quality possible.

If the receiver above is not good enough, could you recommend one for this setup? Budget is around 1k + 1k for the amp if needed (xpa 3).

Room is 13 w x 18 h x 18 l (open living room) and looking to play music + ps4

Thank you so much!
