Low level listening and having good sound at low volumes is way more complex than the power rating of the amp and I would disagree with the amount of power on hand being a useful metric.
Some speakers are "on song" at lower volumes better than others (Harbeth come to mind). Monitors with smallish drivers can take volume for the midbass to catch up to the rest of the frequency hence amps with a "bottom up" sonic signature like Pass are good choices there.
Some amps are poor at low level listening by design (most class D IMO) due to poorly designed input and driver stages typically.
Some cables, usually those with the lowest noise floor, have it all present at low volumes, Allnic comes to mind.
Many integrated amps, even some very expensive ones, can have sub-optimal preamp stages as well which is not ideal for low level listening.
A good consideration would be the Audia Flight FLS 10 listed here on Agon currently. If its anything like its sibling amp than it's a winner. Not likely they cut corners with the preamp stages in that integrated and the amp section is from the FLS 4 which is a stunner.
