I have the HD595 form Sennheiser, and my question is about songs well produced -every kind of music- that makes me fell that i buy a very good headphones whith clear mids and hights, and deep bass. complete albums too of course. i asked for that composition or album that you say to yourself wow, i like this sound as heaven . I have a good amp and a good euipement -onkyo- this is no problem. Any suggestion, i like too orchestral influences and piano and violin compositions. thanks.
