I have listened to the Dynaudio C-1's with the Simaudio I-7 integrated. They sounded fantastic together. I don't personally care for the Mac and BAT equipment, but that's just me.
What I would do if I were you is take the Special 25's to the dealers and listen to each of the four brands and decide for yourself.
