Nah, the 3F does have some glare that shows up in some places like vocals. Burn in does not cure it. That's why I have posted that I prefer the Non-fazored 3 better, even though the Fazored version is more clear with better imaging. Tonality is always priority one for me. (Along with lack of fatigue.) I do listen to both versions though. I prefer the 3F with a warmer cable like a Black dragon or an older Apex cable that I got a long time ago and is no longer made.
(In the LCD4 thread, I asked if the new LCD4 has the best of both worlds and does not have glare, and the responders have said yes to this.)
I'm thinking a Norne cable would be good, as is was for my former Hifiman 560 (it relaxed the sound nicely), but I have not heard it with Audeze.
