^ This. Audio Control make some of the best interfacing equipment out there currently.the Audio Control pieces are just what you want.
What is the difference between the signal out of the PAC and something like the LC8i?
I don't know too much about OE signals.
The best answer is to read up on both. I have used both, but the LC8i will offer a far superior signal and performance. There are some great write ups on Audio Control and their products.
