There's no way anyone else can tell you how loud or how much power you would be using unless they are there in the room with you. It is totally possible you are experiencing what you say.

Sony receivers have been known to be under rated and not up to spec with their advertised ratings. If you were to get a Denon or Harman Kardon both with very good amp sections you would do very well. You could stay around the 100 watt range and be within the range of the M3s.
