I picked up the Focal Clear Professionals this morning, and I really like them. While obviously more listening is warranted, they are pretty much exactly what I hoped from a tonal perspective.
I have been on an IEM kick lately, and have been predominantly listening to my 64 audio A18s I got in November. I have listened to these commuting to and from work every day for 4-5 months and they kind of screwed up my other headphones as the tonal balance is so good on them. It's caused my other headphones not to sound right. It could also be that my brain burned in so much to the A18 sound, that I need some time to get readjusted to other sound signatures.
I put these on and they were really close to what I wanted from a tonal perspective. I only have solid state amps and was listening through an Auralic Taurus Mkii. This made these slightly too hot with some recordings. I then listened through my V281 single-ended, which took a little too much off the treble, and finally my Simaudio 230HAD. That's how I am listening to them right now and it sounds just about perfect.
This surprises me as I never really have gotten into a dynamic driver headphone (outside of HD600). I had an HD800 for a few days but returned them because they were a bit peaky and my 009 did everything they could do but better. I have a Fostex TH900 but its never been my favorite. While some of my planars and electrostats do things better - these compete with all of them because, at least based on initial impressions, I like the tonality of these the best of all my headphones; they sound a lot like a full size version of the 64 Audio A18.
I listened to a Utopia very briefly, but it was out of a poor source so never got a good feel for it. If it's any sharper than the clear - I think that would be too much for me. Nonetheless, I'm now very curious about digging into the Focal line a little more and am curious the ways the Utopia surpasses it (if it does overall). I think I will give it another audition. That said, this is definitely a keeper. It's easily the best dynamic headphone I've ever heard.
