Anybody upgrade their Zu Omen DWs to Souls?

I'm betting my amp will work with the Souls. I really don't want to trigger the need to change it to suit the new speaker. I've corresponded with them about the upgrade logistics and it's about as good a situation as you could ask for. They don't credit you with your trade until they receive/inspect them so it's entirely your decision when to send them back. If you can make the finances work, you can keep the ones your trading while you audition the new speakers (also carrying the 60 day trial period). If the new ones aren't working for you, keep the trades and send 'em back. Can't beat that.

I'm sorry that I can't offer more advice.  Please, keep us update on what you discover between the two or please PM me.  I'm in practically the same boat.  Thank you.

With what information is available, and the generous terms, I decided to trade up. A set of walnut cabinets are already handy so the wait will be minimal. I'll update this when they have had a chance to tell me they do or don't belong in my listening space. 

I just added a pair of the Zu 10 ohm speaker loading resistors to my set of dirty weekend's. I power them with a Manley I pod Stingray and was never happy with them. The Stingray is set at 5 ohm output and the Zu's at 12 to 14 ohms,  so I figured it was worth a try.  After hooking them up the sound totally changed for the best. They flatted out and softened up a lot. Synergy between amps and speakers is way overlooked. This change in sound was much grater then any tube rolling, cable changing ,room enhancing I have ever done.
