Hello! I am a new user of D7000 I bought this D7000 because of D5000. I listened D5000 with my iphone in Denon shop. And i bought in the internet. I expected that D7000 is better than D5000. But Sound is little bit different to me... Because I liked D5000 more. D5000 has more boomy bass. which is i enjoyed. and D5000 treble doesn't make my ears hurt. D7000's treble is strange for me. This is so high that my ears hurt. Sounds like screaming. So, This is not comfortable treble for me. Sounds D5000 is much comfortable than D7000...
