I've had about a week of time with the CO demo unit and what a week. The clarity, separation, and tone are amazing. I generally prefer dynamic drivers but the CO is challenging that hard. I still prefer a darker overall tuning for every day use, but the CO's air and clarity are a breath of fresh air when I'm in the mood for a change. I see the Caldera and Atrium models as an amazing complimentary set of ZMFs for those who want variety. The Atriums are darker, thicker, more euphonic and romantic sounding. The Calderas faster, clearer, and all around more of a analytical listen, while still being highly musical and engaging.
The CO in particular is making me revisit my playlists, digging deep into tracks I've known most of my life, to find hidden bits of detail here and there. I'm really enjoying it so far, and know at the end of this demo either the CC or CO will remain with me. I'll just sell one of the kiddos to fund it!
I tend to listen mostly to "fun" music (code word for crappy studio quality), with a handful of audiophile worthy test tracks. But truth be told those tracks are boring the heck out of me. Anyone got some killer tracks they can share that will show off the full capabilities of the CO? Sharing is caring!
