I have the Magico S1 mkI and am very happy with them in my 12x17 room.
I replaced the very fine Revel F52s with the S1s and was amazed at the difference in resolution and speed. I was using a Simaudio 600i with the F52s. As good sounding and dynamic as the 600i is, a few folks suggested the S1s needed more power to really be at their best so I upgraded the 600i to a Pass X250.8 and Simaudio 740P preamp and this combo with the S1s is amazing!
