I said nothing about throwing anything away and 20 years + is not planned obsolesence. There are lots of high end speakers that are no longer supported by their manufacturers. The owners find a way to keep them, if they want to. There are high end parts that are no longer supported by the manufacturer and if there is a market, someone takes over.
Pragmatically, we can't expect ML to continue making panels for older speakers. We have become "spoiled" by ML's excellent service and loyalty to its customers. But all things come to an end.
I am of two minds on this issue. On the one hand, ML has made promises (albeit by a previous owner) about supporting future panel replacements. Also, they have set a truly admirable customer service standard that has attracted many newbies, delighted many veterans and spoilt all of us. It has been part of the ML experience. if that changes, feelings will be hurt.
Equally importantly, the notion of discarding anything so significant as a loved, high end speaker when it appears to be functioning in most aspects is basically nauseating. Its the same reason my wife and I always share an entree at restaurants these days - waste nauseates us, and it ain't about the money.
On the other hand, I have empathy for the burden that this support might be on ML. How profitable/unprofitable is manufacture of obsolete panels? Given the already low volumes in high end, chances are that older panels are pretty unprofitable, and an irritant - but thats the price of promises. And the price of espousing a technology that has a 10-yr shelf life ynless replaced.
Would I rather see them go under, than support old panels? Obviously not.
If this is not a significant burden for ML, I would strongly encourage them to continue supporting older panels - and frankly, make a big deal about it. Its a responsible, customer friendly strategy and they should get credit for it. Looking at just the margins, and not the long term effect, would be short sighted
if this is a significant burden for them, i would encourage them to look at other ways to support older panels. Maybe they should encourage and support the 12 laid off people to start a company that makes older panels. Maybe they should train and license Graz et al to take on the challenge of supporting these panels as well.
More i think about it, I sort of like the second idea. There are many entrepreneurs with greater passion and lower cost to operate that could support older panels than ML itself. They would enjoy it more, and have a greater chance to make money of them.
