well the potential is there most deifnately, just takes some adjusting to smooth it out? what are you using as your source? something on the warmer side helped with me, my iPod Classic 7th gen, with the equalizer set to hip hop really cut the harsh and sibilant mids to start out with, and the contour switch on the GS Voyager also had to stay shut off, because that adds to the mids and highs, but the ZOv1, along with the Voyager as stepping off point for the sound really was my sweetest spot for the sound that I've been wanting!!!!!!! but now Ive moved onto the MDR7550s, and there are more balanced with more mid centric, with none of the harsh and sibilant mids of the 600s, but in the end after 7months of use the harshnes was no longer there, but I like the mids of the 7550s more, what i also did was to use the filters that came along with my Head-Direct large bi-flange tips, also filtered out the harshness alot, without comprimising the sound at all, so equalise the treble spike of use a warm sourece, I like the sound of the iPod Classic line out,
