Mmm... that's a fair point mate. Didn't see it that way, actually makes sense. Yes, we're taking risks in buying this sort of exotic gear, no doubt.
Over the years, I've noticed that many audio brands don't support older gear, they simply don't have the resources...
OTOH if ML is supporting older gear by making particular stat panels for its valued customers, that's outstanding support! I would certainly have peace of mind knowing that for another 20yrs at least, I could get CLX panels. However, another 20yrs I'd be an old fella, accurate hearing wouldn't be too flash... hence I'd be looking at downsizing anyway.
I think Magnepan is another company that would supply ribbon tweeters for older panels if required but when it comes to ribbons and stat panels tech, thank goodness there's a small group of techies here who can refurb these, and they do a marvellous job! So if and when that time comes, I'd know who to call only if ML can't offer further support. Hopefully, they are able to train new people all about this stat tech so that they can provide the necessary support. The sad thing is many of the younger gen simply can't be bothered with it.
Damn, I should have learned that trade...
