I have heard both the speakers, but at different place and time. So cannot really compare directly. But the listening impression with the ProAc D30RS was so impressive that I decided to go with ProAcs. The new ProAcs are absolutely not bass shy. I listened to the "Thanks to you" by Boz Scaggs and the speakers did not seem bass shy.
Eventually I went with the D48R model that I currently own and love listening to at every opportunity I get. ProAcs seems to get that midrange so right. And I am with @jperry on D30RS and small room.
