I always think of the recordings by Ansermet and the Suisse Romande Orchestra; by modern standards, the sound could be pitiful, but the musicianship shone through in every phrase, particularly in French repertoire.

What a beautiful orchestra it was...
But the good news is that I recently heard a recording by the Suisse Romande Orchestra conducted by its current music director Marek Janowski: the symphonies by Franck and Chausson. Not the elegance of Ansermet or Jean Fournet or the power of Charles Munch, but not a bad recording at all.
