What subwoofer do you have?
Pretty much the A9s and LSI15s need external amplification. The A7s and A9s are practically identical if running with a subwoofer.
Since you are basically upgrading everything,
LSI15s for more music than movies
Rti A7s for more movies than music, with a good subwoofer
Rti A9s for more movies than music, no subwoofer
