I really don't like ATC i personally find them boring BUT that's by design. think of them as a RAW photograph they have no grading or contrast applied they are a tool TBH. And if you really like that then that's fine.
Nopiano is correct don't believe everything that is thrown around. and both your points are kind of correct.
It's not that they play better louder its that they need a healthy turn on the volume knob to get the drivers moving, in turn, meaning you need a healthy reserve of power on tap, so wattage. They will certainly give an amplifier a hard life.
They are certainly not low volume listening speakers the same way for example revel are/is.
If it were me you need to go and listen to them and compare them to more lively designs. Infinite baffle inclosures don't need to be this hard to drive and don't need to be as overbuilt, though out of budget look at the klipsch heresy 1 2 and 3 all sealed and all much more lively.
Nad 3080 comes into my mindAre you asking me?
If I went NAD, I'd go pre and power using the C275 with the matching pre or grab one of there THX monster amps form back in the day
to really take them by the horns, they would give all the control you'd need for the ATC's
I am currently using curved SCM11's and they pair perfectly well with Naim Audio's Uniti Nova.
