You will clip the amp, you need,more power, sure low volumes will be great, if a good song is on, you will clip the amp, regardless of what people say.
Had so many lower powered receivers, amps, past 35+ years.
We will never look back, and must have min of 300WPC @ 8ohm, doubling to 4 ohm, and so on….
you will need the headroom for crescendos and when you want to use the volume a bit..
those stratos mono,amps are very high current, do not let price persuade your decision of purchase.
enjoy themPass 25, she is a great amp for sure, we were watching a pair of monos several years back, Pass labs, 250Wpc, monos, we decided o n something else with gobs of power and headroom.
