That doesn't sound like a situation of overdriving at all.
Have you had those speakers that 'loud' in your listening room before? Reason I ask is that if not, perhaps the higher listening volume is reacting more with your room and you're hearing limitations of the room's ability to accurately present the sound.
My last acreage had a room that sounded reasonable at low levels but anything even close to moderate levels of the past (the past being in a large 50 ft x 35 ft or so living/listening room) it sounded like sh*t. Some weird low level slapback echo, other odd issues. Down with the volume a bit, and back reasonable.
