Speakers sound too bright.

The nails on a chalkboard sound. Once one hears it, it’s near impossible to unhear.

It may seem like a crazy question, but how long is your speaker cable? 

These speakers have a rising top end from 7k up when pointed at your ears. Pointed straight ahead, though, they measure much flatter. If they still sound too aggressive pointed straight ahead, you might check out something like Dynaudio Evoke 30s or Emit 30s, which I'm betting would be more balanced and less fatiguing. 

I’m using the metal jumpers that came with the speakers. My speaker cables are 8ft.

i’ll try positioning them straight. 
 

They do have better dispersion and soundstage than my KEFs. It’s just the harshness than I’m struggling with. Maybe they just need to be broken in. 🤷🏻‍♂️

My personal opinion is you have a very open and telling speaker system now. I think you are hearing a problem somewhere else in your system 

 Break in will help but basically for me it is rare to go from ugly to great. Certainly new speakers sound held back and times settle in and detail comes out but a drastic change is rare in my mind. Don't get me wrong there can be huge changes but just not from unacceptable bright to wonderful perhaps on the first couple of hours. If you have a friend close by that can bring some different wire or components 

 I would try that. 

Good luck regards. 

Y net is your speakers are more resolved than a bunch of your equipment.
