Hello, head-fi people! I'm stuck with the same old question - Shure SRH440 or Grado SR60i. My main concern is that I wear glasses all the time and I'm not truly sure about these headphones ergonomics. Mostly I listen to 70's rock (Led Zeppelin, Pink Floyd etc.), blues rock (B.B. King, John Lee Hooker) and soul. Ocasionaly some trance and rave tracks. At this time I'm thinking of buying Shure 440 and in future upgrade them with 840 pads. As I was reading another threads I noticed many good reviews about Creative Aurvana Live which are cheaper alternative, but I'm not a big fan of bass. Does the bass there is so noticable? P.S. Do I need to start thinking about sound card if I'm going to use these headphones on my PC with 320kbps *.mp3 and .flac? Now it's motherboards default.
