I have the Marchand XM-26 and XM-9. My XM-9 uses upgraded OP2134 op amps instead of the stock op amps. I am using Sovtek 12ax7s in the XM-26.Overall, I would say the XM-26 sounds very slightly rolled off to me in comparison to the XM-9 but otherwise I think the 2 units sound similar.
The XM-44 and XM-126 can be configured as 3 way crossovers and both share similar architecture with the XM-26 whereas the XM-9 is a somewhat simpler design. One thing I don't like about the XM-26 is that it picks up more noise than the XM-9, probably due to its high (1 Megohm) input impedance.
As far as single ended active crossovers are concerned, I don't think you can go wrong with either the XM-44 or XM-126. You can order the proper filter types from Phil Marchand, he is very willing to work with customers.
I use my crossovers with MG-IIIas. When I owned Typmani 1Ds years ago, I wished I had an active crossover like the XM-44/Xm-126 to use back then! Good luck!
