Allen, another welcome/Happy Birthday! The amount of power needed depends on several factors: the sensitivity of the speakers, the size of the listening room, the distance of the listener, the average listening level used, the dynamic range of the material being played, etc. These speakers will use about 1 watt at a comfortably loud average level and brief split-second peaks would of course use much more. In the vast majority of cases any of the receivers having ratings in the 100 watt area would be fine. Keep in mind that power ratings are logarithmic, not linear. This means that the difference between 100 watts and 200 watts is exactly the same rather small 3dB difference in sound level as is the difference between 1 and 2 watts or 10 and 20 watts. The difference between the 130-140watt and 100-110 watt ratings you may be considering is only a dB or so in maximum sound level and is unlikely to be significant in real-world use. Base your decision on features and price, rather than power ratings.
