I acquired a Focal Clear a few weeks back. If you look at various online reviews then you will see that driving these phones from OTL and other high impedance sources is not recommended due to the upper bass hump it causes.
What I can tell you is that the Clear sounds awful with the stock TU-8200 until you bypassed the parallel 180 Ohm resistors. It is not just about the bass that gets bloated, but also the treble becomes veiled and the dynamics suffer.
Unfortunately, connecting the phones directly to the speaker output has a couple of drawbacks. First, the the background noise and hum will significantly increase. Second, the risk of damaging your phones as well as your hearing is much higher. I suspect Elekit implemented these resistors for protection but it does not come without a cost.
The 8200R has adjustable output level so if you install a pair of let's say 3.3 Ohm/1W resistors instead of 220 Ohms, you should be fine with lower impedance phones. Modifying the original model is a bit more complicated and I haven't done it yet as I am not sure if I will keep these headphones.
