If 1 watt can produce 93dB in those speakers, 24 more would drive them to uncomfortable levels. More power isn't your issue.
Keep in mind that SPL is at ONE meter. Inverse square means that every doubling of the distance, the source will be 4 times lower in volume. And also remember that a 6 db increase in volume requires 4 X increase in power.
That said, every amp is not created equal. I had a Decware Torii II that sounded anemic with 96 db Spatial Audio X3 loudspeakers. But it sounded excellent with 104 db Klipschorns. In theory, it should have worked with the Spatials, but in practice, it did not.
