For female vocals Florence + The Machine live are good. Florence Welch's voice is strong, present and nicely "flexes" with the band. From whispers to going full blast. Then add a proper Soul or Jazz diva, the kind of lady who could sing an audience into silence like Aretha Franklin, Lynn Collins, Jill Scott, or Sharon Jones. Pick your rendition and medium (vinyl or CD) and you are done with these two.
Your midrange to highs are covered. Included are interplay with the band and conviction. When the vocalist has fun or really (seems to) means it you hear it. When the audio gear sucks the life out of the performance then that is a bad sign.
"Dance To The Music" by Sly & The Family Stone should make you dance, not die. Audio gear that fails this has no right to exist in my opinion.
