I'm not sure what you consider "insane/high end" but I'm one that found the M1060 on the boring end compared to my LCD-2F and I found the M1060 to be a bit boring in general but its important that you know that I have much brighter headphones like HD800, HD700, T1gen1, HE560, RS2e and my system is:
DACs: UD301, Bifrost Uber, Bifrost MB, and Modi2uber
Amps: Asgard2, Lyr2, BH Crack, Project Ember and headphone outputs of UD301 and AH01.a few others.
While I don't own a M1060 I have two friends that have them and tried them a few times and they have never really gave me a "WOW' experience but since we all hear differently its hard to say how you will perceive the M1060
