are you using those speakers for both music and home theater?
if so, you might want a separate ’front stereo system’ (integrated with HT Bypass feature),
and an AVR with Pre-Out.
best of both worlds.

in that case, the front integrated get’s the advantage of the 803’s higher efficiency
the AVR, enough for the center and surrounds, there you go.
you might think about changing to higher efficiency for the smaller speakers rather than buying a bigger amp for low efficiency ones.
