A while back, I may have heard that Magnepans were owned by a
surprising percentage of Stereophile subscribers, on the order of
20%.

But are Magnepans truly "High End"?

Why wouldn't they be?

Too practical

Too reliable

I have never heard anyone say they were too reliable.
Ten years ago, they were known for separation of the wires from the
membrane, which limited the lifespan of a panel to three years or so.
I heard that the manufacturing process improved, but I don't know what
the
result, in terms of improved reliability, is.

This delamination is indeed fairly common. I have a pair of MG-1s that
has this problem in one area of one panel (they had this problem when
I bought them at a steal of a price). I've read about quick fixes of
injecting the appropriate adhesive at the appropriate points, but I
don't know the particulars.

You find them listenable inspite?

They're really not my cup 'o tea (the MG1s I mean). They aren't bad,
but this particular speaker just doesn't have the presence that I've
come to expect from better Maggies. That's another reason I haven't
been in a huge hurry to fix them up.

Is there any evidence that the problem has been fixed by a change in the
manufacturing process?

I think it depends on the model that you buy. Ribbon tweeters are
pretty cool. I don't think that mine even has quasi-ribbons.

BTW, I have a set of Acoustat 2+2's, which while different in execution, are
similar in concept.
Since the Acoustat membranes have no wires, they do not suffer from
delamination.
The membranes are known to sag, but apparently, a hair dryer is enough to
tighten them up again.

IIRC, a hair dryer is a component that I forgot to mention in the
procedure for fixing the Maggies. I think that sagging was the main
problem with the Tympanies.
