Hi Ken. This can be a little tricky, especially since the magnifiers and
correction eyepieces are expensive accessories.
Firstly though it is possible that your Tele Elmarit 90 could benefit from
adjustment to the M8/M9 standard at Solms (or NJ I guess) Tolerances are
much higher and error that might be un-noticeable on film or inconsequential
can be more visible with sensors (and pixel peeking at high magnifications
on your monitor). If it has not been serviced within recent years you may
consider a CLA? Some careful, controlled testing will tell you the story
anyway.

When you use your M9 normally, do you wear spectacles?
I guess that you know that the finder has built-in minus half a dioptre?
This has the effect of giving you a virtual image two metres in front of the
finder. Our eyes are generally comfortable focusing a little to use that. Or
we need further correction (eyepieces and/or spectacles) of course which is
based on your distance correction numbers (for spectacles). You may want to
visit your friendly optometrist/opthamologist first and try your camera with
the temporary test lenses. You might find that a correction lens will really
'pop' that finder image into clarity for you.

The 1.25x and 1.4x magnifiers make the image larger rather than change that
virtual distance. So they are meant to make it easier to detect differences
in the alignment of the two images at the rangefinder patch (and also make
the frame lines larger of course). Anecdotally the magnifiers also include
some further dioptre correction, alhough this is not documented anywhere
that I can see.
So the executive summary is that the best course is to look through a
magnifier with any extra correction you may use (eyepiece and/or glasses) on
your camera with your eyeball ;-).

I actually have both, having got them used at more reasonable prices. The
magnification is at the cost of some eye relief, a little contrast and
luminance, as well as field of view of course.  This is more so with the
1.4x. That one protrudes further and gives more of a tunnel vision effect,
inevitably. My view is that the 1.25x is a better choice/compromise. It
works well for me with 75 and up. I never use my 1.4x now in practice. Both
do allow me more precise focus with the longer lenses if I have my camera on
a tripod and am working at a critical setup (wide open, in close). By more
precise focus I mean I can see tiny alignment errors at the rangefinder
patch that I don't see with my unaided eye.

Depending on just what you are shooting, the anglefinder actually offers by
far the clearest, sharpest (higher magnified) image of all (of the central 8
or 9 mm of the finder). It is not at all suitable for general photography
though.
