cd's/SACDS to test highs?

For me female vocals, cymbals and violin are the litmus test for highs.

I always listen to Rachelle Ferrell's "first instrument" for female vocals. There are many excellent SACD's with very well recorded solo violin (e.g. Bach partitas), and numerous Jazz trio recordings with great cymbal work (Lenny White is usually quite busy on the cymbals).

Not sure what genre you're into, but there is an incredibly beautiful "classical song', with very high female vocals (but not opera style) interplaying with a violin (Gidon Kremer), on the Arvo Part album "Arbos". The song is called "es sang for langen Jahren". This is another staple recording of mine to evauate "highs".
