As the title says, has anyone taken them up on that program?
I've only seen one thing where someone listened to a regular model and then the X version.
The verdict was the two speakers sounded different from one another but one wasn't preferred, just the sound was different.

Would love to hear feedback on the X series,

I did a DIY version for my LRS.

Here is my DIY version for the MG-III that upgraded the cross over caps, eliminated the external crossover box, and made a more rigid connection to the base. Not shown are lead bricks on the base and the top of the panel.

The Magnepan design and construction invites modification. However, based on what I have learned, the X modifications go way beyond simple crossover upgrades. In fact, I'm taking a hard look at the 20.7x.
