Anybody upgrade their Zu Omen DWs to Souls?


I'm looking at my options to use the full trade in value of Omen DWs towards something higher in the Zu lineup. From where my finances sit, the model that makes most sense is the Soul. I'm wondering just how and how much different they would be from what I have. It's a little less clear cut since my ODWs have the drivers from the 08 Druids, not the current models. My amplification is a Audio Nirvana 6V6 (12 watts) which drives the ODWs with impunity. My musical taste is diverse.  Thanks for any insight.

The jury has returned and the verdict is in. Souls win! They needed a couple of weeks steady (10+ hours/day) break in to lose some treble grain, but thinking they had improved enough to decide I did a comparison with the ODWs this weekend and the Souls are very compelling. If you read John Darko's review of them it's pretty spot on. The ODWs are very good speakers, especially for the money, but the Souls are next level good. I had every intention of sending them back if they weren't worth the extra cash, but for me they are. 
@audiewww Fantastic.  Glad to hear you like them.  I will re-read this review.  My DWs will ship this week and I can't wait to hear them.  Thank you for sharing and I'd love to hear any other observations as they continue to break in.
@audiewww Now that you have had some more time with the Souls, do you have any more observations to add?
