On Clears, which are open-back, the top end of most recordings is just fine for me with the Silver Dragon cable. I use these at my desk, where I run Roon from an iMac to Schiit Audio gear, including the Loki 4-band equalizer. Occasionally, on some recordings, I boost the mid-bass and midrange a tiny bit. I’ve also experimented with the Harman Curve for the Clears (see this thread: DSP for Focal Clear Headphones)
The other advantage of the Dragon cable is that it is much less stiff than the stock cable, which also had the annoying habit of transmitting any “rubbing” against my clothing as noise to my ears.
