I second that. I received my Khan right before CanJam NYC and brought them there to compare with other IEMs including Solaris. Solaris had similar signature as Khan, but I liked Khan better on every aspect, especially beautiful mid and articulate treble. I am very happy that I got Khan. That being said, thinking about the price of Solaris, I think Campfire did a great job.I have the Khan and compared it to the Solaris at the show. I felt the Khan had deeper and tighter bass, and a little better highs and overall presentation. The Solaris is very good. I just felt the Khan was better. This could also be because the Khan fit a bit better than the Solaris on my ear. I still think the Andromeda is Campfire’s best all around IEM. I also still love my Custom Encores. You cannot beat the custom fit. I hope this helps with your decision.
About the fit, I totally agree with you. Solaris is too big and uncomfortable for me. Also Khan has better isolation to my ears. YMMV.
