Zu Essence upgrade kit - worthwhile?

I speculate it is worth it for someone who is already invested in the Zu Essences, especially guys with custom finishes, that enjoy the ribbon tweeter and don't prefer the Soul form factor.

I upgraded the drivers in my Definition 2s to the nanotechs (be prepared for a long burn in!) as well as the high pass network to Clarity CapMRs and both upgrades were substantial.

I've never heard the Essence, but apart from people not enjoying the ribbon tweeters performance as much as other Zu speakers, my understanding is the biggest qualm was comparatively less dynamics.

The nanotechs should address that and the full griewe implementation should lead to some great low end performance.

I bet it sounds like a lot more then a $750 upgrade

Gopher thanks for passing along your thoughts.

The website indicates the upgrade drivers have gone through 600 hrs of burn in, so that should help.

Gopher, I'm thinking about the upgrade for my Omens. Care to share more detail about your experience? I would love to know about the differences you heard.

Yes.... It's worth it. I had mine installed by Sean when he was in town about a year ago. We are very satisfied with the results, as the Zu sound that so many said was lost, is now back, and very enjoyable.

I really liked the Essence as they were, they were missing some of what my previous Druids had in the upper registers, but the bass was better. They were very enjoyable, but now I feel that they are a great speaker. I believe that if they would have launched them like this, instead of the "dialed back" drivers (to mate up to the ribbons), they would have been a bigger hit.

The nano-tech drivers are something....
