Yeah I understand that a higher impedance output is supposed to color the sound over a low impedance output. But what I'm hearing isn't a uncolored vs colored sound; it's a lack of clarity and precision and bloated bass from the low impedance output. So if my ears aren't playing tricks on me, which I'm quite sure they aren't because the difference is extremely obvious, I'm wondering if this is only because of the design of the Geek Out that's somehow causing this. Granted, this is only happening with my IEMs. When I use my low impedance AD2000X straight from the 0.47 ohm output, they sound great.
