I am interested in participating in your contest; I own, and love, my Monster Miles Davis Tributes.
I listen to many genres. Mainly Rock and classic rock. I like a lot of the new alternative hybrid genres. Subdub, dance, and other techno. Jazz and classical. Jpop, Koreanpop, and Mandarin. Hip-hop/R&B (mostly major hits), and a lot of rap. (rap in the not so R&B form like immortal technique, cannibal ox, Wutang Clan, Cool Calm Pete, Rakim, etc.). Some Reggae.
I have a tube set-up (friend's darkvoice), a SS amp (Zero DAC/AMP, Pico, Lyrix Total amp), and portable gear (clip+, Ipod, HM-801). I can compare it to my full-size headphones (fun JVC HP-DX1000), or portable over-ear cans (ESw10jpn; as good as any full can). Or one of my many IEMs (UE triple-fi, Ime6, V-moda) and earbuds (Ok1, Pk3).
I could even compare to my Yamaha receiver, speaker set-up. (or listen to it from the receiver).
Of course using lossless audio format (FLAC), or 320 kbps mp3.
I listen for casual purposes. I have no professional reviews, besides my casual reviews via posts on forums.
