Well I’ve never bought Mac and Sonus Faber only used in a good deal.
Personally, nothing much to lose and maybe something to gain, but I can understand the concern.
If quality of new Mac and SF were to go down as part of new marketing strategy, I would expect that to only increase the value of existing classic Mac and SF gear.
That plus Mac and SF have their unique aspects that many fancy but far from the only fish in the sea. I'm not really concerned that I may not be able to find good quality hifi gear for good value moving forward as needed.
