Totem Dreamcatcher vs. Arro

I Currently have a pair of Dreamcatchers that I am using in a 2 channel setup. They have really impressed me. I was originally thinking of getting a pair of Arros, but found the Dreamcatchers first and bought them to hold me over until I found some Arros. I must say that I'm so impressed with the DCs that I'm not sure if I should buy the Arros now.

I think the mid is the same on both and the DC use an MB Quart tweeter. What are the differences sound wise between the two? Is an upgrade would be worth it?
