I've used a 6-watt chip amp, a 6-watt tube amp, a 30 watt chip amp, a 40 watt chip amp, and currently a 30-watt SS amp with my 626's in a large room. All these amps had no problem pushing the speakers, even at robust volumes.
Currently the speakers are in my folks house with a 125-watt SS amp.
Either choice will be just fine.
