They're not particularly fussy. Reasonably sensitive at 88db and not dipping below 4.6 ohms according to their specs.
How much power depends on what kind of music you listen to, how large your room is and how loud you listen.
In a smallish room, 30 watts would probably be minimum if you like to listen at reasonable levels, but not particularly concert levels.
For larger rooms and/or realistic concert levels or for widely dynamic music such as symphonic orchestras, 100+ watts wouldn't be too much and you would likely want to add a subwoofer.
I've used 15 watt amps with similar speakers in a smallish room with no complaints, but I don't listen to music all that loud anymore. I probably average around 82db these days.
Post some room measurements and preferences for loudness and you'll get a better response from the membership.
