Hi @Protegimus, apologies for my delayed response.
Yes, I have M2. But I did not hear them before buying! I was trying to settle on what colour to order for S3s (having undertaken extensive listening trials at dealer and at home between S1 and S3) and whilst I was trying to decide on the colour of S3 - Magico launched the M2, so I figured they must be better? Also they were slightly less dominant visually in the room.
