So my GH2 came in...
And for those of you who prefer the light wood....I don't think so. Cocobolo and Rosewood remain supreme. Checkmate.
Two more photos, including one that has a knife and a handgun (with cocobolo and rosewood) in them (didn't want to offend anyone), along with full resolution pictures, can be found here: http://imgur.com/a/P37Qz
Funny thing is, although I obviously enjoy rosewoods and cocobolo, that wasn't the deciding factor. At least not consciously. I'd been looking for new headphones for use in my office and kept coming back to how much I liked my Alessandro's. On my big head they are comfy, and I enjoyed the sound. So decided to get a Grado and had a hard time picking in the $600-$1100 range. Took a chance on the GH2, mostly because they were the latest. The cocobolo was just a bonus.
Only a half an hour of listening so far and I really enjoy the GH2. I was expecting a bigger soundstage and other nuances, but two surprises were the sibilance being less (compared to the Alessandro) is quite obvious. And I also had to adjust the volume up a bit. They both have an Impedance of 32, so not sure what is going on. Other than my ancient headphone amp is anemic (which I already knew, that'll be the next change soon).
