How loud do you listen in how large a room? (I'd recommend you use a meter or phone app to determine your listening level as one person's "moderate" volume may be another's "loud" or "soft".)
If you are a 90 dB or 100 dB volume listener or using them in a large room you'll probably run out of power.
Example, I have a pair of 88 dB sensitive Ohms that I power with a 20 watt/ch Aegir in a 15' X 24' room. My average loudest volume is 85 dB (C weighted) and have no problem with peaks. However, I do use an active crossover that cuts low bass to the Ohms and have a separate subwoofer. This takes a lot of the power load off the Aegir.
