@inna - I heard the Focals at the last audio show in LA and they were top of the line along with two other makes, playing through Headamp amps and a Holo DAC. The other two cans were from Audeze and HiFiMan. To my old ears, the HiFiMan cans were the most balanced. I could listen to them all day. The Focals had more emphasis on the mids, which made them stand out at first, but I noticed less emphasis on the highs and lows. The Audezes came in third: they just didn't do it for me.
They were all nice but after hearing the HiFiMan cans, the flaws in the other two became noticeable. There's been lots of progress even since then with newer models so the best thing you can do is try them out before you plunk down the cash, and make sure you hear them through what your listening with.
All the best,
