I prefer my vocals to be at about 6-7ft in height such that they are standing at a lifelike height or on a small stage similar to noromance’s post just previous to mine. That was my biggest gripe when I owned Wilson Yvette -- while the speakers sounded great (albeit too beefy for my room), the tweeters pointed down slightly to simulate a point source with a mids, and it made it sound like vocalists were sitting. No thank you!
I should also mention that my listening chair has a reclining function, which I like to use slightly so that hearing a taller soundstage feels more comfortable and natural.
