If you can arrange for an in home trial- you can get a better idea of compatibility with your amp, room, music and "ear". A lot of stores will loan out stuff for a week or so, especially if you put it on a card and refund on return. Worst case arrange to pick up their demos on Saturday (with a card charge & return/refund plan), play with them for a day or two (specialty stores are often closed on Monday, or have minimal traffic). If you can, try to get two or three pairs of your favorites at the same time to compare.
