At Very low listening levels with very efficient speakers, (101db) Is my solid-state amp AB using just A power?

Two speakers increase of sound pressure by 3 dB, doubling listening distance from a speaker reduce sound pressure by 6 dB. Doubling the amp power output wattage increase sound pressure 3 dB.
Its depends on how far is your listening distance and how much class a power your amp has before it switch to class b.
