My Magico S3MK2 are powered by 2 Luxman M900u amp (using C900u pre-amp)
without knowing your room i can almost assure you you will get improvement in all aspect 9more refined sound, more dynamic and micro dynamic, plenty more details and control over the speakers)
a friend of me have the same combination (Luxman 900 series amp & pre + Magico S3MK2) but also Mackintosh MA 9000 he use to power his focal speakers on the other room.
one day we switched the amp just out of curiosity, so we powerd his Magico's with the Macintosh, the Luxman combination was far better to our ears
