I got a knock on my door a couple hours ago and surely enough it was the UPS driver... lo and behold, D7000s are here!
Gotta love the box, it looks about as good as it does in pictures. The phones were surprisingly lightweight, a very solid fit without excessive clamping. Can't decide which one is comfier between these and the HD650s. D7000s look real classy and smell great to boot
Do these need a lot of burn in? Maybe it is my amp again, I will have to try it with my SS amp. Bass is definitely tight and nice, not bloated or overabundant. If fact, call me crazy if you will, I think the bass is a bit lacking at my normal listening levels for highs. In other words, I feel there is too much highs that it becomes a bit painful to listen to if I want to bring the mids and bass at the desired loudness. Soundstage is on par with HD650, meaning much wider than AD2000s. To me though, tonality matters more it seems. Some EQing might be in order.
D7000 is ok, but I kinda prefer AD2000 at this moment even with its poor comfort factor and just a tad light bass. In the end, I liked HD650 with alex's cables the best out of the three. As for D7000 being closer to HD650 than AD2000, I will have to disagree; D7000 sounds quite recessed in the mids, which is the biggest difference I notice. To my ears, AD2000 sounds similar to HD650 with a bit more coloration, whereas D7000 sounds totally diffrent.
I also had a new cable for the HD650: double helix "molecule". At first listen, it sounded a bit smoother and extend on top, but I kept noticing highs were too distant sounding with absence of airiness. Kinda remided me of canare starquad DIY cable I had earlier - refined, smooth, just a bit boring and felt like something was missing.
EDIT: I forgot to mention D7000 sounds very refined, I think I will like them a whole lot more if I could tame the highs. EQing it is then.
