Violeta,
It seems that if you really don't know what you want specifically other than a high quality can, the best and safest place to start is with the Sennheiser 580's*. No matter what, with these you cannot go all that wrong. Chances are you will like them very much, even if they don't remain your favorites forever. Near Senn HD600 sound for a relative "song" (pardon).
BTW, have you checked out jwf2's advertisement in the ForSale/Trade forum? At that price you could afford a decent amp (from HeadRoom, maybe?) and really be able to evaluate them. If, for some reason, they were not your cup-of-tea, they would be relatively easy to sell afterward or just keep and get something with a different type of sound.
*(I have not personally heard these)
