"Harshness & glare" are not words ever expressed by those who have heard the Essences here at my demo room.
I HAVE heard statements like "Best Zu sound I ever heard" on many occasions, however...
Including similar statements by one of their respected set-up people.
The Essences replaced the Druids here.
To be fair, the Essences were/are final prototypes - perhaps the production units could be different, but that seems so unlikely, once they had settled on the design parameters.
And I was using a Method from 40Hz and below.
But the Method wouldn't have changed the upper mids and treble. If anything this speaker is smooth, smooth, smooth on top.
Not sure why we heard such a difference.
