Mine Atticus just arrived! I got them from TSAV on their recent sale. Mine came with both balanced and SE.
Initial impressions are very favorable. The timbre on these is incredible! Acoustic guitar and vocals sound great. These mids are addictive.
I'm listening to The Chain by Fleetwood Mac the guitar and the soundstage / instrument placement during initial section is really impressive. There's an initial guitar off to the left but then a cowbell strike hits out even further off to the left. The bass guitar at 3:04 comes in perfectly in the center with excellent timbre, followed by the electric guitar cleanly separated off the left again.
So far the Jotunheim / Mimby is a great pairing with these. I tried these with an iFI iDSD at CanJam this year and the treble seemed a bit off/veiled. I'm not hearing any of that from the Jotunheim / Mimby.
Very pleased
