either really. I do believe that an honest 120wpc with decent dynamic headroom and decent power supply is plenty for your excites. cheaper AVR ratings are more optimistic than a decent power amp or integrated I would think. A fun experiment is using an amp with VU meters and reallize your peak program power is usually under 10 watts and probably 1/2 watt true RMS.
Anecdote the first: old NAD 2030 was purchased for 60$ rated at 30wpc, probably more like 40-50 IRL, can drive my old contour 1.8 to surprisingly high levels even with loudness contour turned on which adds alot of wattage in the bass where the speakers can handle it
Anecdote B: Bryston 100 wpc rated integrated (~200
s) Can drive my C4s to insane volumes even in a big room, quite sure it could fry some smaller excites before become stressed
Anecdote the 3rd:tried to drive my buddies contour 5.4s with an old 100wpc receiver. Something cheap I forgot which model, but old enough to have a linear powersupply and class AB. It shut itself down at low volumes. Didnt like the 4ohm nominal load I guess.
Anyways, dont get so caught up on rated power Id say. Using a decent 2 channel amp or int is highly preferred but the joy of this sort of thing is you can upgrade over months, years, decades. There are alot of decent amps that arnt all that expensive. Like The Schitt yonson recommends. A decent integrated with HT bypass seems like the hot ticket to me. Not being a home theater kinda guy I personally would be tempted to skimp on the HT components and focus quality on the stereo components. A low level AVR can drive some pretty inexpensive and efficient klipsh or JBL horn loaded speakers to high volumes.
