@Shane D I've not had a problem using SE on the LCX, in fact most of the time I have my Elex in the XLR, and my FOSTEX TR-X00 plugged into the SE jack giving me a choice of open or closed, and interestingly they seem to be the same volume level so fun to swap between the two.
I rarely use equalization so have never pursued a Loki. It could certainly balance any perceived flaws in the music.
Where had you found the LCX to measured horribly? Again tough to hear some measurable spec differences.
In the end it is all about what sounds good to you
