For a setup like yours, I’d say you don’t need a ton of wattage, especially for nearfield listening. I’ve run similar speakers on an old 45W integrated amp, and it had no issues giving solid, clean sound even with a bit of headroom. If you’re sticking to around 80dB, a 40-50W amp should do the job well, even for movie watching at moderate levels. Honestly, I’d lean toward a used Yamaha A-S301 or something similar—they’re pretty reliable, and I’ve seen them pop up for under $200. But if you want to stick with a receiver, older Denon and Marantz models are great finds too, especially from that mid-2000s era.
