Hi, I'm just getting into classical music, have found the various threads here with recommendations for Beethoven symphony sets, Mahler, etc. very helpful. I'm after recommendations for recordings of Mozart's Requiem please. Also, I'm in the process of setting up a headphone system for listening to classical and jazz (my tastes are somewhat broader and extend to Arcade Fire, The Police, RadioHead, Dylan, Neko Case, Joanna Newsom etc. but I find myself coming back lately to classical & Jazz). I'm currently considering purchasing ATH-AD900s headphones that will be connected to my ipod and home theatre system (fairly standard panasonic DVD player with a decent Onkyo amp). I will upgrade from here with a headphone amp and a decent cambridge CD player (Azur 640c V2). Do you think this will be an OK set-up for enjoying classical music? Thanks for advice and recommendations. Update: I just found this thread and will probably try and get hold of Nikolaus Harnoncourt's 2004 recording on Deutsche Harmonia Mundi.
