Headphoneus Supremus
I tried the Atticus and Eikon on the Feliks Elise. I liked it with the Atticus, but not the Eikon. The Atticus changed sound signature more, and gained a good bit of staging, but wasn't the great experience I read on several reviews. I liked both headphones more from my Jotunheim. I sold the Elise. I don't fault either headphone, I don't think the Elise was for me to begin with.
OTL amps are fuller, richer, and warmer in general- especially when compared to a bright solid state amp like the Joti. The two are like polar opposites. However if you get used to it with the right high impedance headphone (eg. HDxx), they are magical. They are certainly not for everyone, though. My Aittcus and Eikon are here, going to give them some play with my uber Glenn OTL and Apex Teton this weekend.
I will be very interested in hearing your comments...glad your amp finally made it to you
