Debussy's Opera, Pelleas et Melisande

Just finished listening to the Media Player(1 miniute) offerings of a few of the avaliable recordings of this opera by Debussy. The recording that struck me most in terms of emotional involvement was the recording made back before our time, Desormiere conducting the Yvanne S.O. The Karajan recording was far superior in terms of acoustic engineering. Though the Desormiere recording is very poor quality, this is the one i will order. However there are 2 others made by French conductors that were not offered on Media Player, and am curious about these. If someone has a collection of recordings of this opera, please post your notes. Frankly don't see how any conductor could present the opera with more understanding than does Desormiere.
