Seconding two already given recommendations:
1) Charles Munch's 1955 recording with the Boston Symphony Orchestra. - remastered, should be on Sony Classical (budget), and has not been 'bettered' - you will only find 'different'
2) Boulez / Berlin Phil recording. Pierre (and contemporary engineering) gives a crystal clear reading, with every instrumental part in balance, and yet each clearly audible in the texture. This is more like 'looking at the score.' I find it amazing, but more a clinical and intellectual pleasure.
The Munch is also amazing, intellectually but too on the sheer visceral / sensual plane.
So, I'd most strongly recommend obtaining both recordings... and have fun!
Best regards.
P.s. (The Monteux recordings are more of 'archival' interest because he premiered much of the early 20th century repertoire, including Stravinsky's Rite of Spring!)
