The Utopia's instantly clicked with me, probably my favorite pickup so far. I like them more than the Evos and Gravity Storm on my other rgs/jems (haven't tried the evo2 or breed, I know I know!). They are actually hotter than my Sonic ecstasies in my Majesty too.You are right. The Utopia's are hot, but I don't find them to be harsh. I do find them a little more sensitive in my attack vs. the EVO's. If I play softly, they clean up nicely, and when I play more aggressive, they sound dirtier.
I agree with the others that maybe pup height could help, and also try experimenting a bit with how the pups respond to your playing (if you haven't already). And of course lastly, it is possible the Utopia's just aren't your thing and need to swap them out to something that meets your ear.
Oh....and congrats on the PIA!
