..or a little EQ.
And a DAC/amp that has better synergy with the HEKse. As many have recommended, a warmer amp +/- warmer DAC will pair well with the HEKse. Warm vs. cool DAC may be a point of contention with some who think all DACs sound alike, but when I switched from a Schiit Gungnir Multibit to a Holo Audio DAC, I could immediately use the HEKse without as much EQ because the treble was attenuated and bass was a little thicker. On top of that, a warmer tube amp (may also depend on what tubes are used) will be likely bring the biggest change. Couldn't stand the HEKse when I trialed it a couple years back with a Liquid Platinum. With my current EC Studio Jr and warmer Gold Lion 300B tubes, everything is perfect for my ears that are pretty sensitive to treble.
Full leather earpads are interesting, and I'm looking forward to see if this helps tame the treble even more. With ZMF pads the full leather pads can add some unpleasant treble peaks, while suede types typically are a little smoother, despite being overall brighter/more neutral.
