I have Magico S3's and really happy with them, my friend has also s5's, driving them with Krell FBP 700x or cx and using ARC ref40 for pre, and full transparent mm2 XL cables sound is great, i learned that magico's S series are going really down ohms as 1,25 or 2,5 so you have to use a powerful amp. I think no one says that they are something worse for Magico's, if you can do proper setup really they are good speakers!
