Note on stands, for my money the factory Stax version is the one to get. I just got a Sieveking Omega stand from a Massdrop sale. Looks really nice, but frankly isn't that practical. It stretches out my Stax headphones,
out of their natural resting state. The Stax cover also doesn't fit on as well. The Stax stand is made from Hokkaido wood (and looks better in my opinion), and has the Stax logo to boot. The Sieveking comes with a useless cloth bag you throw in a drawer. The 009 in particular loves to be on a Stax stand. The two ear cups naturally clamp onto the stand.
I also have a vintage Store front Stax stand I use for when I step away for a moment. Maybe I'm just a Stax guy at heart
