One problem I'm finding is that dialing in sounds that work for FOH and/or my FRFR monitors at gig levels don't translate well to my Audio Technica M3 + 1964ears V6s custom molds (also using DL32R)...if your sound is well dialed in on your fractal and the PA is properly tuned, the FOH tech shouldn't have to do much to your sound, maybe a bit of high pass and low pass filtering that's it. You can have your cake and eat it too, but it means getting your sounds and levels right, that takes time and effort.
I may have an advantage in that I've made my living as a live sound engineer for a long time. My XLR outs feed the console, usually my Mackie DL32R and that feeds the FOH and my Sennheiser EW 300 g3 in ears, no custom earbuds and it sounds like my nearfields at home. Having good accurate monitors that you know and trust makes a huge difference.
The other thing that I've found in getting a good live sound is playing at stage volume if you using either amp and cabinet, wedges or an FRFR monitor. If you don't, you'll skew the frequency response because of the variations due to the levels your playing at ie. Fletcher Munson curves. https://en.wikipedia.org/wiki/Fletcher–Munson_curves.
But all that being said, you have to try till you find what works for you, your comrades on stage and the sound tech, not an easy feat
Mostly I suspect this is FM at work. I have recently added a frowny face EQ on my aux send master output on the DL32R, as well as a bit of extra reverb. That seems to help.
