I switched from a MOTU ultralite to the K-Mix and haven’t looked back (I hated the motu). It sounds decent to my ears, it’s tough, handles modular signals easily, so you can go straight out from your rack, and basically everything you can do with the editor can be done from the unit without the need for a computer, which is a big plus, but I do find if I’m not using it regularly I need to consult the manual to remember key combos for changing things like stereo pairing of channels and the like. Super flexible in terms of standalone mixer/audio interface/midi control surface, etc etc. Overall, I’m super happy with it, and looking forward to getting it out for shows more often, as I haven’t done any since I got it.
