Finally, I can join the club!
I had been on the hunt for a set for a while, then turned my attention to specifically looking for a 4-screw (2010-2013) set. That was a terrible idea and added so much time. Luckily though I found a semi-local buyer and snatched up a nearly mint condition 4-screw for a pretty decent price right when I'd decided to stop looking for a while
They have some of the nicest bass I've ever heard. The impact and tactility are fantastic. I do think that for technicalities the HEK are better. But damn are these 'phones fun. Lucky I don't have to choose between them.
I'm running them balanced, but tested single ended of the same amp too and clearly preferred balanced. Unfortunately I have to wait several months to try them off my Xindak A600 speaker amp, is packed away from a recent move
Anyway, still lots to listen and figure out about the headphones, and then to mod, but for now I'm damn impressed with them and I'm so happy I stayed in their trail.
