So I have the HD600, HD650, DT770 250ohm, and the Sextetts are on their way. I will probably end up selling or trading either the 600 or the 650 at some point.
 
Because I am building a Crack amp which is best paired with 100ohm or higher headphones, I'm trying to figure out what I may like to try next. Ideally, something that contrasts the style of the Senns. I really don't know where to start.
 
I've been curious about 600ohm DT880 or DT990, but it seems like it could still most "sound like a beyer" vs my other beyers. D2000 has always made me curious, but I'm looking for high impedance. I love the look of the SA5000, but have never heard them, and I am ideally wanting to buy something used or under 300 new. This pushes the SA5000 out of range most likely, as I've never seen them for sale used on here.
 
What am I not thinking of?! Help me out!

I wouldn't dismiss the DT 880/990 especially if you're looking for sound signature that contrasts the Sennheisers.  Now for some additional high impedence options-
 
AKG K 500/501, K 601 
 
Hmm, there doesn't seem to many high impendence options.  You'll probably have too look at older headphones for more options such the AKG's K 501(120 Ohms).  They've long been considered among the best heapones AKG ever produced.
