9.5" MADI AD/DA-converter?

hei folks,
i’m a happy owner of a RME Madiface Pro. It’s an amazing unit - and for keeping my setup small, i’m looking for a MADI-AD/DA-converter that has only half-rack-width. Such units used to exist for ADAT, but for MADI i couldn’t find a single one. Maybe one of you guys knows something?

cheers. timm
