There are no line inputs, so I don't really know how to properly connect the GAP. I don't think it's even possible with this interface? Is there anything cheap I could buy to fix this? Perhaps I'm overlooking something. This stuff is just for my private mobile rig so no big budget I'm afraid heh

He just turned the inputs on the Firepod all the way down and used it as a converter, and used the API as the pres. Granted, there was no A/B comparison b/n this setup and a line-input setup, so who knows how much better it would be if the Firepod wasn't involved, but the end result was a fantastic sounding EP. And it was WORLDS better than just recording on the Firepod.

So, I've been thinking of doing the same thing with my MOTU 8 Pre, but I don't have a quality pre to test with. It does feel a bit like shooting yourself in the foot putting unnecessary things into the signal path, but ultimately, it comes down to whether you can make good recordings with what you've got, and that route definitely worked for that project.
As far as I know Line Input still colors the signal, because you are taking the signal through the interface circuitry. (Yes, you do have Line Inputs. You have a XLR/Line Input combo jacks like me, so that means if you plug a TRS cable into the input, it treats it as Line Level Input Signal, and bypassed the XLR input, so the impedance changes as well. Example: I have Saffire Pro 40 with the same combo jacks, and it goes like this: Mic: 3K, Line: 10K)

There is nothing odd about plugging a signal from the pre-amp into the interface, because the pre-amp amplifies a mic level signal to line level signal, so the interface will have a line level signal coming in, that you need to have in the first place, unless you want to use the interface pre-amps instead and it will do exactly THAT, but without your stand-alone pre-amp.

It will most likely color your signal just a little bit, but that may not be a bad thing.

On my Focusrite Saffire Pro 40 the pre-amps are very clean, so it barely adds anything when I come out of my pre-amp, into the interface.

I wouldn't stress at all about it. That's very normal.
