New to amps but the E12A is what I chose. So far not too impressed - sorry! Soundstage is flat and bass sort bleeds all over in a muddy way. Volume bass kinda maxed out and meh. Using cable it came with, an iPhone, and 1More e1001 IEMs- which I'm also not thrilled with! I was trying to keep it economical but obv I gotta spend more. Would a diff connector help?I may not have the ideal setup
Your IEMs are not the best, and you're double amping the signal. You need something with Line Out to feed the signal to E12A to take full advantage of its sound.
