I really like crossfeed, music sounds more realistic to me and after that I
realized I need all the mentioned settings. I have achieved fantastic
results with Koss KSC75. Anyway, my archive consists of Musepack encoded
music, so can I say CPU intension is higher when EQ is enabled on Musepack?

I thought slow reaction comes from memory load but I do understand now it is
about complex EQ settings tiring CPU. I'll give it a try for HW EQ. Thanks
in advance.
