This is my first post. I have the AH-D7100's and so far have been very happy with them. They are my first pair of high end phones. I received mine on August 1st from Crutchfield who apparently had them in stock long before anyone else that I could find. I was going to get a pair of AH-D7000's but decided to wait for these. I have never heard the 7000's. I believe my phones have been used long enough now to be considered broken in. I paired them up with Headroom's Desktop Amp (the $850 model). I think they are awesome. Everything I own sounds like I'm hearing it for the first time.
The bass is clean with a punch when its intended, mid-range is balanced, and the high end is clear. You hear everything. Voices have a real sense of presence. The soundstage for me is not too big, not too small. A friend tried them out and he said they sound like he was in a stadium so I guess there's something to be said for how each of us hears sound.
I don't care about graphs. I'm not a machine.
I listen to all sorts of music.
Lot's of 60's, 70's and 80's pop
I realize judging phones is a very subjective thing...just like lots of other stuff. For example, I own a 350Z and when I saw the 370Z I was horrified. I suppose if I had owned the 7000's I would be disappointed with the 7100's. That's just the way it goes. If I had the money, I probably would go for a pair of the Fostex TH-900's. Not because I'm not happy with the Denon's but because I know there is always something out there that's better. Maybe I still might. But I have heard there's a diminishing return on phones as you get past the $1500 mark. I wonder if it's really worth it.
