Here's some more information on using class A from the Pass Labs you might find interest in Kasperbergholt. https://www.passlabs.com/technical_article/leaving-class-a/
I can understand you're interest in this mode of operation and it's effect on quality. I was the same about OTL tube operation. I went that route but made a commitment also with my loudspeakers and went from mid sensitivity like yours to high sensitivity to better engage with the lower wattage of tubes in general and specifically OTL tube amps. You'll probably be just fine with your choice of Parasound amp you choose. They get great user reviews. And your equally well praised speakers will need those extra A/B watts for when you turn the volume up.
P.S. I have an older 90's vintage Parasound amp I've used with home theater.
