You may wish to try some Viktoria Mullova's albums, she's a skilled and sensitive violinist. Her Mendelssohn, Tchaikovsky and Sibelius concertos are a nice treat. Good sound quality too, specially on her ONYX label albums.

As for lovely lady singers, Melody Gardot is becoming lately a favorite of mine, along with Alice Russell Pot of Gold is awesome.

Thanks guys ill definitely check them out

Thanks Kirosia Ill definitely check it out.

+1 for Nalick.

1. Bjork- (most of them are very good, recording wise, varies)
2. Florence & The Machine- Lungs
3. Sarah McLachlan- Afterglow, Surfacing
4. Madeleine Peyroux- Bare Bones, Careless Love
5. Carla Bruni- Comme Si de Rien N'Etait

1. OK
2. NO
3. OK
4. NO. They are brickwalled and some distortion is present. MoFi version is good though.
5. Haven't heard it.

My solid recommendations are for the following:

Classical:

1) Symphonic Dances, Vocalise (DSO, Johanos)
Reason: Minimalist recording with exceptional sound quality. The cheapest version sounds great. The more expensive SACD done by Kevin Gray is exceptional. Very dynamic!

2) Discoveries (Simón Bolívar Youth Orchestra of Venezuela, Dudamel)
Reason: Fantastic music (like Danzon No. 2) which you might have never heard. Recording is VERY good. Subtlety in the sound with plenty of nuances to keep the most discriminatory ear happy. Mastered well.

3)The Four Seasons (Connecticut Early Music Ensemble, Kipnis)
Reason: Famous, well liked music. The flute concerto drops some SERIOUS BASS. Well recorded and well mastered. Get it while it's still cheap!

Female Vocals:

1) Various - Casino Royale OST
Reason: The Look of Love as sung by Dusty Springfield is to DIE for! The best version to get is the one I linked to. The entire soundtrack is great for audiophile demo reasons but that one track is mastered very well and the sound quality of Dusty's voice comes across as being realistic on good speakers/headphones.

2) Billie Holiday - Songs For Distingue Lovers
Reason: Aside from the awesome music, this particular stereo recording sounds very realistic and the sense of space on the recording is fantastic. Billie sounds on top of her game on this album and on the right system, she sounds like she is in the room. The stock pressing sound great but the version I linked to is just in another league.

3) Ella Fitzgerald - Clap Hands, Here Comes Charlie
Reason: Terrible cover art BUT....Amazing recording...and..it's Ella. 'Nuff said. Serious demo quality as far as vocals and music are concerned.

4) Heart - Greatest Hits
Reason: Great music to rock out to (Crazy on you)!!  Their vocals sound very natural on this mastering and it's definitely one you can crank up and enjoy. Great recordings from when artists could actually sing and perform live without the aid of post-process fixes.

I think that should be enough hurt on your wallets for now....
