When you want to test your tweeters air and extension, what type of music or intruments are you looking for.
Thanks!

Just listen to a range of music you like. You'll know pretty quickly if the ribbons are more extended and sweet than what you're used to.

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).

Edorr, Rachelle Ferrell "First Instrument" is excellent! Try Dianne Reeves "I Remember."
