I think an obvious hint would be that the supreme version has real wood veneer whereas the earlier ones had vinyl covered cabinets.
Perhaps system matching is important, as may of the compliments praise the bass and volume of sound coming from such a small speaker, not just the usual sounds good with jazz and vocal comments that you hear every time a new mini monitor gets well reviewed.
It is possible that the Minuets are just another good monitor with some good reviews - there are many - but hoping they had some genuine magic about the design, especially because they are so small.
My EPOS ELS3's were played for about 30 minutes before I put them back in the box and in storage.
