I used to own focal Utopia with my Euforia, and lived with my friend’s clear as well. Tbh, I find they’re both very exciting, the clear is like a consumer headphone on steroids, huge wow factor. But I find the sound fatiguing and much prefer the atrium. Mids are fantastic, bass is fantastic and with these tubes the treble is fantastic in its own way too. Not insanely detailed like Utopia or susvara, but enough detail and done in a relaxed and nice way.
I think the most important part is how it makes you feel. The clears make me want to stand up and dance for 30 minutes, then take them off. The atriums feel like a chest rub that brings out a deep sigh of relief. Nothing hurts, just a soothing cuddle.
Edit: oh and they’re insane for vocals. I get the feeling that the singer is singing to me personally.
