Magico speakers are evolving rapidly: older designs tend to be very analytical and IMO possibly overly so.
Starting with the M9 they are trending towards musicality with more natural tone and detail.
The A5 and S3 Mk3 and now the new M7 all use the 5” midrange debuted in the M9. Perhaps that is largely responsible?
I bring this up as the discussion of suitable amps is largely affected by this recent trend with Magico.
