Proac Response D30 DS

I currently own Proac Studio 140MKII which I’m very satisfiedwith ,sound is detailed and punchy soundstage is vast and dynamic are terrific I run it with McIntosh pre / power system with good results .
In the past I considered upgrading to Response D48R but realized that my listening room is relatively small and maybe I will have to upgrade to better McIntosh power amp to move them properly so decided that the D48R is really not for me.
I am considering now an upgrade to the Proac D30 DS( the dome tweeter version because I understood that dome tweeters last longer than Ribbon ones ) but no chance to make a demo in my country. I guess the overall sound wil be improved-more transparency,details and better soundstage- but I am afraid that moving from 2.5 speakers to 2 way ones will reduce the dynamics and bass I already have with my current Studio 140 MKII ? Is the the D30 a substantial step up over the 140 MKII ?
