How will they sound? I have the FiiO E07K right now and there just not enough for me. I know the HD 598 are low impedance headphones meaning they don't need to be driven and are easily.
I'm looking for very Clear Highs and powerful (Not earbleeding), and Some pretty warm and detailed Mids. I'd also like alittle bit bigger sound stage
I don't want to buy new headphones.
