Proac Response 2.5 vs D25 vs D28


Hi,

Since I do not have the privilege to compare them and it seems that there are no reviews of the D25 and the newest D28 has someone had a chance to compare those models although the 2.5 and the D25 are not manufactured any longer.
I really liked the Response 2.5 and I consider buying the D28.
Does the D28 outperform the 2.5?
Any answer will be highly appreciated.
