The Loki certainly seems well worth trying. One downside, though, might result from the fact that it only provides unbalanced inputs and outputs, and presumably has an unbalanced internal signal path, while I believe both of your Pass components are fully balanced.
In any event, if the Loki proves to not be to your liking, and you would be willing to consider spending several thousand dollars on a remarkably versatile and transparent solution, you may want to consider a DEQX, www.deqx.com
It accomplishes equalization via sophisticated digital signal processing, without the traditional side-effects and limited adjustability of analog equalization, and can do a whole lot more than just serving as an equalizer.
Most models provide digital inputs and outputs as well as balanced and unbalanced analog inputs and outputs, as well as the ability to select between multiple sources, so inserting it into the signal path before or after your preamp are both possibilities that could be considered. Some models can also be used as a preamp, which is what I do with my DEQX HDP-5.
