I'm in the mood for something with better bass. Yes, my LCD2 does bass well enough, but too lush sounding but has a rather narrow soundstage that, well, compared to even the DT990/600 (to me anyway). I'm thinking HD700 or HE500, the former has great soundstage, better attack and decay with a more extended bass compared to the HD800. The HE500 would be a fun can for gaming and movies, but I'm concerned that it'd sound too much like the LCD2. Is the HD700 different enough from the HD800 to justify a purchase? I believe I can get a HD700 for about 500USD with one more year of warranty left.
