Hi Pierre,
sure, but M32 Pro AD and DA are the newer products. 1 RU, internal blower (noise is load dependent and has been optimized by Firmware patch), dual power supply, MADI and AVB are supported.
I recommend you to take the HDSPE MADI FX because of the special driver design that only uses system resources for active audio channels in bundles of 8 ports.
See my review here and the PDF therein: http://www.tonstudio-forum.de/blog/inde … Pro-FS-BE/
Theoretically you could also base on AVB but then you would also require AVB capable switches.
I personally think that you have still advantages to use MADI as it is a dedicated cabling infrastructure for audio and the MADI recording interfaces bring some additional i/o ports that could be useful.
The current rme avb and Dante recording interfaces are much to the point without AES, adat etc.
