Quite a coincidence... my visits to head-fi are also rather limited for quite some time now, plus I got back to the basics... rediscovered my love for the original M-100, bought two units (in white, my current favorite color for equipment...) plus XL pads -- after completing my color palette of the CF2W Codex that is. What can I say... I still love the M-100. Long version of this story can be found here:

Only toy that is still tempting me is the Shure SHA900... I always loved its design. But would I really use it enough to justify its rather steep price (maybe opting for a returned unit in this case)?
I'll let go some units from my collection, especially the Pioneer Master-1 and the Shure KSE-1500 (still the best headphone I know, but I simply don't use it anymore). I think the D9200 will stay, its just so good. Although I did not unpack it for almost 2 months right now...
The APM will be allowed to stay, despite me never using them. Interesting case... I was really waiting for an Apple headphone for literally years. Finally it came, it even sounds good... but I don't use it. Really don't know... sound signature would fit me almost perfectly (pronounced deep bass with good clear structure), its quite comfortable (although a bit heavy)... I just don't feel compelled to pick them up. I mainly keep them for the easy switching between devices for videos etc. Really strange...
The DT770/80 will definitely stay. Although I became more aware of its slightly troubled treble lately, I still like this one. The iconic design, easy repairability and robustness appeal to me.
I'll also keep an AIAIAI configuration, based upon their better Bluetooth headband (supporting more codecs than the current offering) and the S05 driver with the pleather over-ear pads. I like AIAIAI for the modular concept (pure genius) and their approach to sustainability (they even publish repair guides).
My K812/K872 will also stay, the last models from AKG Vienna. Plus I like them.
The Austrian Audio Hi-X55 may also be allowed to stay. To me its really comfortable, and a prime example of what level of build quality is possible at a reasonable price while still keeping production in Europe (mainly Vienna).
The Shure SE846 will stay. Love this one, plus the TW1 Bluetooth adapters gave it a new life. Sound is still sublime, and just stunning given their age.
The 64audio N8 will of course also be with me, and not only because its a custom IEM: I use them daily while taking my walk(s) (in ancient times also commutes) and just marvel at what sound quality is available on-the-go. They helped me save so much money being customs...
That grew longer than anticipated... just a short closing note: to reach me just @ me, I might not check in that often.
