I have the Mobile Pre. It is not without it's idiosyncrasies, but once you get the hang of dialing in the gains and levels, it is a good sound card. The built in phantom power was the main reason I got it. I use it with the ECM8k and even built a jig to check speaker impedances and resistor values with it.

Their tech support is also very good. Whenever I have had an issue, they have responded very fast (and thoroughly).

Good luck.

Well, the tech support calls I made were about specific gain values and input impedances. Stuff you won't find in the manual, but that I needed to know. Nothing was about the function of the unit.

The only problem with the calibration file was that there is no easy way to loop the XLR balanced to the tip-sleeve input (unbalanced). You can use an adapter, but then it's not an apples-to-apples calibration, since the adapter will force the card to use the XLR in unbalanced mode.

This all being said, I just ran a 1/4" instrument cable from the tip-sleeve line out to the tip-sleeve line in and did the calibration that way. It is identical to the one I did by making an adapter cable.

The only weird part of this sound card is the adjustable gains for the inputs. It adds an extra complexity to setup balancing system volume, input levels, and then the line-in/mic gains. But once you get the hang of it, you can set it up for new measurements almost automatically.
