Best female vocal recording on CD?


i am a sucker for great warm rich smooth female vocalists, especially on tube gear and speakers that image well. but i am almost always faced with a great voice/song but a sonically inferior recording (examples too numerous to list) or a great recording of a mediocre voice.  rickie lee jones (pop pop) comes to mind- fab recording, but come on lets be honest about her voice. however, i will almost always pick great recordings and leave the bad recordings for the car.

 so i am asking for what you use as a reference female vocal recording/track. right now i come back tp bonnie raitt "you cant make me love you" from luck of the draw.  big, warm, strong voice. not a perfect recording. but hmmmm that voice.

my only requirement is it has to be on CD. and we all know of great vinyl that did not translate into great CDs.  so help me out here, what should be my next music purchase

THE SOPRANO Arleen Auger possessed a pure-toned voice of great flexibility and absolute accuracy of intonation. She excelled in the music of Monteverdi, Bach, Gluck, Haydn, Handel and in particular of Mozart, but also sang works by 20th-century composers such as Carl Orff with great success. Also consider the amazing Dutch soprano Elly Ameling and the very fine American Barbara Bonney.  Don't let the idea that these are "Classical" artists keep you from your investigation.  Like a fine Scotch or Beer, although new and distinctive at first they will soon become favorites.   
Also, give Halie Loren - Waiting in Vain, Priscilla Ahn - Dream, Izzy Bizu - Diamond, Macy Gray - Annabelle a listen.  Some different names....
Oh yeah, Mary Gauthier is a fairly new discovery of mine. I have a couple albums of hers, still have to get the one produced by T-Bone Burnett.
Ok, I’ve come back with new discoveries, I think you need a female voice, a piano playing, and your ears to listen to these 2 songs to complete a story and journey on your own, note that the recording is not available on YouTube, you can try download somewhere else:
