Got the blackwoods [...] Early days yet though, will update as I get more thoughts.
I just received new blackwood Eikons as well -- with the intention of replacing the teaks I already have (thanks @Daanish for the tip on reaching out to Zach directly on this ).
I only had to listen to them for two minutes to decide I need to stick 'em in a shoebox, set the pink noise track to auto-repeat, forget about them for a week, and only then start listening to them for real. Fresh out of the box, they have zero magic compared to my already-burned-in pair. Maybe this is obvious to current owners, but I figured it's worth a quick comment... Anyway, I'm not stressed about it; been through this routine too many times, eh heh. They really do look great though!
