I'll start with a few audiophile discs. In my opinion, it's hard for these tracks/discs to sound anything but good.
The Hunter. Another of her albums,
Famous Blue Raincoat, seems to get more press, but I like this one better overall. The track "Way Down Deep" is very nice. I read somewhere (maybe the Madisound board) that the drum is centered about 60 Hz, making it a good bass resonance test.
Holly Cole,
Don't Smoke In Bed. "I Can See Clearly Now", and "Cry (If You Want To)" are my favorites, but the entire disc sounds fabulous.

I'll second Mary Black. The lady can sing. My favorite disk is
The Holy Ground, particularly the tracks "Flesh and Blood" and "Dockland" (which has a nice sax solo).
Some other good sounding discs:
Angels Running or
A Gogo. Great guitar playing, good, natural vocals.
Suzanne Vega,
Solitude Standing, "Language" (all sorts of interesting background instruments) and "Gypsy" in particular.
Neko Case,
Blacklisted, "Deep Red Bells" and "I Wish I Was the Moon". Alt-country meets film noir. She has a big voice, and the album is sort of dark, spare, and moody.
Paul Simon,
Graceland, "You Can Call Me Al", etc.
Loreena McKennit,
The Visit. "The Lady of Shalott" is the standout track for me. Great voice.
October Project,
October Project. My wife played that not long ago, and I remember noting how great it sounded. Their music sounds like it comes from another time, long ago.

I think my system sounds good with most of my discs. In my case, the final piece of the puzzle was replacing my passive preamp with an active one (Parasound Halo P3). That added some warmth and dynamics that were lacking before.
Also, I think it would be useful if you listed some of the discs/tracks that sound harsh (or bad in some other way) to you. That way, if one of us has the same discs, we can describe what we hear vs. what you are hearing.
