My favs that I can think of, in no particular order:

Patricia Barber - pretty much all of her records sounds great

NIN - Downward Spiral SACD, or CD, With Teeth DVD Audio, and Still

Tool - 10,000 days and Lateralus (the latter is an HDCD)

Miles Davis, Kind of Blue remastered

Stan Getz Joao Gilberto feat Antonio Carlos Jobim

Dead Can Dance - all albums that I have

Jorane - Evapore, and the live album

Lhasa - La Llorona

Radiohead - OK Computer

Peter Gabriel - Up CD and SACD

There are others, but if I keep going, I'll get carpal tunnel
