If you don't listen loud, 6-8 W is more than enough

with 89 dB speakers. Not very loud is 70-75 dB peaks. From rough calculations, you need 4 W from a single speaker at 3 m distance in open space to have 71 dB SPL. Because of room reflections and 2 channels, you practically need about 2 W/channel in a small-to-medium room. I use 14 WPC amplifier with 87 dB speakers, and for normal listening volume is at 9 o'clock, which I belive corresponds to 1-2 W.
Important requirement is though that speakers perform well at low and very low levels. Speakers that specify minimum driving power are not of this kind.
