You're the one with the z5 right?I agree they probably check, just not all the time. BTW I also am waiting for my pair I ordered from them as well . But after buying from Massdrop, Kickstarter, and a couple of items from over seas that took for ever I have grown accustomed to relaxing and waiting for stuff to arrive. I expect I will be seeing the A73 sometime mid month anything sooner will just be a bonus.
If so, I'm looking forward to a comparison in SQ between these two.
Hope you enjoy them!
