Also worth noting the Nine did not push Gandalf over the edge to force him to reveal his true Maiar powers. I can only assume they didn't pose a big enough danger in killing Gandalf, even if he said he was hard put to at Weathertop. Didn't come across as tormented and aggravated at the Council of Elrond than when he told of his dealings with the Balrog when asked by Gimili in the White Rider guise. It seemed more like he thought the Nine were tough, but manageable, but that the Balrog was formidable and a match for him. A shaken Gandalf the White in anguish and emotional pain when telling his tale is one big indication of the might of a Balrog.
