I would completely separate music conducive to meditation, from anything calling it self 
"new age". A lot of new age music becomes boring quickly, and causes you to lose the 
meditative state.

Here are a couple nominee's just from my personal collection:

Alan Hovhaness "Magic Mountain", "Symphony for Metal Instruments", Koke No Niwa "Moss 
Garden" (1960)

Beaver & Krause "All Good Men", "Gandharva"

Nino Rota's Soundtrack to "Amarcord"

Patrick O'Hearn "Slow Time"

Korla Pandit even has his moments, god bless him.
