Proac speakers at moderate listening levels

How is resolution of Proac speakers at more common moderate to lower levels of listening. I have high efficiency Coincidents (94db)which do well at lower levels and am considering the Proac D1 (87db), thus the question. I'm using a new Sugden Class A integrated for power (30wpc). Thanks.
the review below might help;
I have the D-15s. I think they sound pretty good at low levels. I think your amp might be a little on the weak side unless you are in a pretty small room and if you are you probably won't need more than the D-15s or even the D2s. I also have a set of the Tablette 2000 model, and while they don't quite have the resolution of the more expensive models, I think they are overall more fun to listen to.
