Outside for your callow example of internet trolls, the whole purpose of post counts is to demonstrate that members have been actively participating in discussions about audio and have likely learned/experienced a great deal through that participation. So yea.. post count on head-fi can equate to experience (though I don't even think Dubstep Girl was stating that).. I have personally read many comments from Dubstep Girl, Magick Man, and MacedonianHero throughout various threads and appreciate their comments/wisdom/experience. I also remember being a lot more appreciative of experienced head-fi'ers when I was a junior on head-fi (guess times are changing?).
In regards to this thread specifically, I have been following it because of my intrigue about the D7100s as a previous big fan of the D7000s, but i'll tell you what, I am grateful to have read all the comments that these headphones do not come close to Denons previous line because now I know not to waste my time on them. Too often un-experienced head-fi'ers rave about how amazing headphones are without proper comparison or prior experience which can be deceptive to a new-comers to the forum. This actually happened to me when i was new to head-fi and I ended purchasing a horrible pair of headphones based on really poorly executed reviews/comments (I learned my lesson and now ask a lot more questions and read a lot more comparisons before buying).
