To expand on that a little bit, the lemosax units (either with Schoeps 5pin binder plug or not) were all designed to take the place of the pre-amp bodies in remote capsule systems (e.g. Schoeps cmc6 bodies). On the bright side, there are non-Schoeps systems which are voltage/current compatible (or at least tolerable of the lemosax's power) if you can get the right cable terminations.
There are actually a bunch of sx-m2 models. (at least, but not limited to) the standard sx-m2, the "lemosax" for remote systems (sx-m2/ls), the mono output option (sx-m2m), a nagra version (sx-m2/nv) and a Royer Labs version (identical to the standard, except the P48 switch is deeply recessed to avoid accidental changes). There may be more, these are just the ones I've found evidence of.
