I see, that's cool. Maybe changing cables really helps change the sound by a fair margin. Well, I preferred the JH13s over the 16s, because the 16s have waaay to much bass for me. The K3003 are pretty good too, though the bass is also too much for me, but do take my words with a grain of salt since I even find the W4s to have too much bass.
Where are you located?
Yeah, I think cables makes a huge difference but don't use a pure silver cable though with the W4!!!
