I haven't listened to the HD-555, but the modifications described in the following thread improve the HD-595 substantially in the areas you are talking about:

The first modification requires cutting the headphone housing. The second alternative modification accomplishes the same thing and involves no non-reversible changes to the headphone, simply lining the inside of the cups with acoustic foam.
Any upper midrange harshness on the HD-595 (or the 555) is caused by reflections and smearing of the mids and highs from the back of the driver. This can be very easily damped without any reduction in the highs from the front of the driver. Amazing difference in the midrange. Much more apparent bass. Soundstage extends about two feet beyond the headphones. Scary.
Total cost: A pair of replacement foam pads from Radio Shack to carve up (or replacement 580 foams), a bottle of rubber cement, and a pair of scissors. Takes about an hour.
