No, there was no "m" version.

You'll find all the details in Duncan's Meridian Info site (link at the top of the page), and MrMarbach has given you details of how to tell whether you have the mm version in your other thread.

Be aware that Trifield width will not work with the 2.5b9 beta firmware. This can be fixed but at your own risk: https://www.meridianunplugged.com/u...width+568.2mm&Search=true#Post156459

There are also "darker" arts that can be applied to the 568.2mm. Feel free to PM me and we can discuss.

Sooloos, Roon, G series (with LPS upgrade), 800 series (with LPS upgrade), HD621, AC200, Prime and PS, DSPs old and new.

Purdeys, Moke, Leica, 'Blad. Only the best.
