I think the various impressions is also caused by the different volume levels that individuals listen at. Since I listen at relatively low levels (65-75dB) the HE560 does not sound bright to me but if I turn up the volume to 80-85dB the HE560 becomes a bright/harsh sounding headphone and will cause fatigue in a short period.
Agree with @mandrake50 and @peter123 about pricy cables, not worth it for very little or no difference.
