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 ?

Agree with Milpai. As good as the D20 is, the D-30 takes things upa notch or two. You will not be disappointed.

I had the chance listening to the B&W 804D and Proac DT8 side by side it was a big surprise that the modest 2.5 way DT8 didn’t embarrass the bigger 3 way B&W double bass drivers at all they were very close in any aspect with minor advantage to the 804D.
The bigger suprise was that the 2 way D20 with only 1 driver was much better than the 804D with its 3 drivers !
that shows you how great Proac speakers are .
I'm not a B&W fan for many reasons and not all are sound related.  That said, I do feel that the Proac's are better better tonally.  To me, if you can't get the tone down right, then that's a non starter for me personally.
OK you all have me seriously interested in the D48R’s. I use tube components though and the 4 ohm load worries me a bit. I have driven some other lower ohm speakers without issue though. 

  My room is 16x24 so I think I will be OK with them in here. I don’t listen to much music that will push the lowest of frequencies, but I haven’t ever had any issues with significant loading in here normally.
