I noticed the same thing. Before getting a new amp, I tried several things. First, I tried new earpads, what ended up working for me were the Brainwavz round velour earpads after I cut out the mesh inside. Then I used Electri-Q, to dial down the frequency peaks according to the frequency response graph I found at DIY-Audio-Heaven. I also bumped up the low end a tad and then used a fixed gain setting to bring everything down a bit. What I ended up with was this:
Tamed the highs, without losing clarity. After this I noticed that my headphones were sounding somewhat...asthmatic. The Fiio K5 just wasn't giving them enough power. I pored over several amps and narrowed my decision down to the Aune X1S and the A30-D30 topping stack. I only managed to audition the Topping stack and I got the A30 right away, I left the D30 for later. The A30 gives all that extra mph the DT-1990 were calling for, the D30 brought back the harsh treble, but amazing deep rich low end, since I was feeding the audio from the coax out of my Fiio X3-II and the time I had with the thing was short, I didn't play with the EQ settings so I didn't bring the D30 home.
TLR, try the topping A30, wonderful little thing.
The EQ curve should be completely under the 0dB line.
Less preamp.
