The DMP3 outputs line level (-10dB / Nominal / Consumer) via TRS. So probably any interface that takes 1/4" TRS as line input. Which is a good majority of them. Make sure that they allow you to bypass their preamps as not all will allow that. The DMP3 is a TWO channel preamp, why limit yourself to just one channel? M-Audio Mobile Pre would work, but very limited by todays options. Lots of others out there. Emu 0404, That cakewalk thing (UA-25?), and others.
