Hi Marc
I used to have a pair of S5 Mk 1s and changed them for the S7s about a year ago. In short I absolutely love them...a big improvement v the S5s (which were hardly shabby sounding) and addressed the only reservation I had about the S5s viz a lack of heft/body v my previous Wilson Sashas. Interestingly I have my S7s in quite a small room and they work brilliantly. They are being driven by a Soulution 711/725 combo with MIT cables and you would not believe the power and authority these speakers are capable of. My sense is that the S7s have become almost the cinderella of the Magico range with all the attention focussed on more recent additions to the line up! By the way mine are in bronze (like my previous S5s)...to my eyes they look classy but restrained and a nice change from the usual black or grey
I am quite familiar with the 725/711 combo. Man, do they have bass grip. They must have huge synergy with the S7's. I used to own the 520/501's with Raidho D3 V2. They are terrific components.
Best,
Ken
