Listening to the 1963 recordings of Beethoven's symphonies conducted by Karajan (Blu Ray Audio release) on the Clear by way of my Oppo BDP-103, Schiit Gungnir and iFi Pro iCan... I've never heard these recordings sound so fresh and alive. What's more, they sound like they could have been recorded last week!
Somehow, the Clear negates nearly every last ounce of analog tape hiss and yet I find the sound not wanting for treble extension in the slightest. The same recordings on my Grado PS1000e and, to a lesser extent, my HD800S, sound like there's a window unit AC running in the background. How the Clear accomplishes such magic, I cannot tell you, but it's an incredible feat indeed!
I have owned several more pricey cans than these, but I'm thinking that Focal has produced my favorite of the bunch.
