eric has a good point on power quality IF your sound quality varies nite by hite but the SPL and music you are listening to remains constant.
my reference system is bi-amped at 1.2 KW per side, w speakers in the 84 Db class for efficiency, but I never use that ( how do I know ? DMM, SPL meter and an RTA....good tools are cheap, your hearing is not )
I have two other 40 WPC systems that provide adequate SPL for peaks w 86 db class speakers in rooms to 15’ x 35’, of course I dont listen all that loud...certainly no 100 db peaks....
on to your amp, audiogon member contemplating purchase of the 86 db speaker hauled his amp over to my place for 4 hour listening session at levels louder than I normally push - amp held together pretty well and dialed back just a smidge was liquid velvet, its certainly a musical amp. It was running off Isotech power conditioning....
finally for those who dig the high SPL world, get hearing tested....
