Well only a few hours of playing here...but so far the first impression is good.
The Clears are indeed 'clear" but very musical to me....over a wide variety of amps, they seem really easy to drive.
55 ohms, and a high sensitivity....I am having a hard time deciding on which amp pairs best they all are great but different.
From the Burson Fun Class A amp to my Bottlehead Mainline.....such a difference in presentation....
I hate it but they seem more clear with my SS amps than the tube amps....but the Mainlne has an entirely different magical presentation....
Its like there is no perfect answer!
The one thing so far I see as a "neagative" is there so revealing that poor stuff really come thru as mediocre!
The timbre, tonality is really the best I have experienced....that said the HD600's abnd T1's are no slouch here....
PLay some Brian Bromberg, his Wood Cd, Fredom Jazz Dance and the tone of the bass strings is soooo real....and at the end he slides his fingers over them and you can
close your eyes and visualize them.
Also they sound pretty goodand balanced at low volume levels...
I have one neat little amp designed by a friend over in France that has TI's OPA 1622 in it...https://www.diyaudio.com/forums/headphone-systems/304684-ampcasq-opa1622-integrated-headamp-project.html
This little amp really plays with these Clears nicely...
So much has been said about these headphones already,,,for $1499 I thought they were abit pricey and my budget was $1500...but when the price dropped
to $999, these became a very good deal for me...
I will post more, but just want to listen for a few days!
Hats off to Focal they hit the mark!
Note: The Burson Fun sound the best to me with their Classic Op Amps.....the Vivids and Sparkos are just too trebly or sharp to my ears.
THe Classics makes the amp sound "Lucious and Alive".
