Magico seems to come out with a new speaker every 6 months or so that makes a previous model un sellable.....Just my thoughts...
I believe that was the case at the very begining, when they introduced a few models in close intervals. If I recall correctly, they have rolled the Q5s just 2 years after the M5s for example.
They have been bashed on the forums for doing this (not by their customers, btw), which I think made them reconsider their product launch schedule. They seem to stick to 4-5 year production cycles nowadays, which is no different to what Wilson or B&W does nowadays.
