TM, welcome. The 2500 would be a fine choice, regardless of whether the rating is 130 or 180 watts. Keep in mind that speakers such as the M60 use about 1 watt at a comfortably loud average listening level. Brief split second peaks might use 100 watts or more, depending on factors such as distance of the listener, room size, dynamic range in the recording and the average level which one listens at. The difference between 130 watts and 180 watts at a peak, for example, is only about 1.4dB, e.g. 110dB compared with 111.4dB. So no, it's highly unlikely that this small advantage would be needed by you. Give other features more weight than power ratings.
