zu essence?

Any compare the Essence to the Presence? I have read great things about the Presence.

How would the Essence compare to Klipsch? I currently have the RF-7 but am looking at the P-37F (Palladium) as well.

Anyone? I want to try the Essence but want to make sure that they are an upgrade from my current Klipsch RF-7

There's a Zu add in this month's Stereophile , they are going back to selling direct and the price is like $3500 vs $5000 via retail - they note doing this because of the economy

Although a bit late in the day from the original thread.

Using solid state amplification I find the Zu Essence much better overall than the Zu Druid. The Zu Druid to me was a bit too dark sounding in comparison (using my then Naim amplification).
Getting my Zu Essence was a nothing more than outstanding for my music listening experience. The Essence are not as inconsistant as the Druid, in that temperature changes do not affect the sound as much on the Essence as it did on the Druid's.
I have found the Zu Essence to be more of a plonk and play speaker, get it in a reasonable position and it sounds great, a bit more fine tuning and they sound exceptional.

Anyone else have their own experiences with the Zu Essences?
