Comparison: Cowon Plenue D Vs FiiO X3 II
The FiiO II X3 has more power, so it took me to find a certain volume point. But anyway, here's the details I could perceive the sound of both.
I noticed a larger soundstage in the face FiiO X3 II.
The serious FiiO were a little out of control, I found kind of fat and shapeless.
The mids are equivalent in both players.
Treble of FiiO II X3 I found more accurate than the Plenue D.
Overall I liked the result with the FiiO X3 II,...
