I've heard a lot of headphones and I pretty happy with the HD600 which I use 95% of the time. The RS1 is a headphone I've desired but when it comes right down to it the comfort issue is huge with the SR-125's and with the RS1 it won't be any better. The V6 is my go to gaming phone (which I've written about before) so it's more a tool then an entertainment piece, i.e. it's not going anywhere. I did have a brief flirtation with the HD650's but I prefer the HD600's. The sextett though is on the list because I love the grado sound, and if they really will give me the Grado sound with AKG comfort, holy . . .
Amps however, well, there are quite a few amps on my list that I want. Right now I'm stuck with a LD2++ and a maxed out META42
