The Dali Rubicon 2s are great. Ive had the R300, Dynaudio x18, Wharfedales, B&Ws, also able to borrow ATC scm11. Personally still prefer the Rubicon 2 over all the speakers ive heard so far. very underrated brand outside of the EU. I really believe they are on to something with their SMC technology being much lower in distortion than other brands (i think there are measurements in their whitepaper
https://media-dali.azureedge.net/1673/rubicon-whitepaper.pdf). If you listened to the R300 and Rubicon 2 side by side, the Kefs sounds much slower and compressed compared to the Dali. Like the woofers start & stop instantaneously --- I believe this gives them that rhythmic & engaging sound.
They are tuned for wide dispersion and is meant to be listened to wthout toe in. Maybe that is why others may perceive them as non neutral. But in the listening position, they are designed to be neutral. Alpha Audio has measurements of the RUbicon 2 along with their distortion levels, it measures best out of all speakers including ATC SCM11, Dyn x18, B&W 705s2, Monitor Audio Gold :
