- made soundstage a bit larger
- got rid of the lower mid bass cloudiness/veil
- added a very subtle and slight sub bass effect
you would have pure perfection. Regardless of what SE846 does, what I describe above would be GOLD....and it sounds like W60 kind of does this. As another poster mentioned, W4 was much more grown up sounding than SE535 so the improvements from SE535 to SE846 was much larger than it was from W4/40 to W60 (is what it seems like).
While SE846 seems to have the better "wow" factor and the best universal IEM bass in the world, (it seems) the W60 still has a very nice FULL sound but better treble and transparency. Sounds like an amazing IEM.
This sub-bass effect was achieved with the FiiO E12A. Totally. Now you feel it, you love it, its amazing. This amp's Bass Boost focus more on sub-bass. Much more than any other amp I have ever owned. Soundstage also gets a bit larger, so I think its pretty much near perfection. Also got a silver plated cable, which widens soundstage even more.
The lower mid bass cloudiness/veil was corrected by modding the Star Tips which consists in opening 2 holes near the dome with a thick needle.
