I actually caught myself a spot for a second "quiet" drop at around 2AM on February 5th (2019). Was already in the market for an external headphone amp after finally giving up following the endless struggle with my Creative SoundBlaster X AE-5 flagship card combined with Creative's absolute travesty of DAC software suite, Sound Connect 2. Snagged it right then and there, and got myself a Massdrop x LiquidCarbon SDAC/Amp on an in-stock offer to tide me over until the THX AAA 789 ships this May, upon which I'll pipe the audio from the SDAC/Amp (running as a pre-amp) into the THX. The really crazy thing is that only couple of hours later, the drop ended! I was shocked at how fast they went! If you want in on this hardware, I suggest you set up some kind of snipe bot to land you a spot in line for the next ninja-drop!
In hindsight I almost feel dumb having spent so much money on mid-level SDAC/Amp + S-tier Amp with balanced 4-pin cables, and not investing more in the actual cans I'd be listening with (HD58X). Current headphones are amazing, I don't know what I'd even look towards as an upgrade, so I can't wait to hear what the setup sounds like with the THX addition in May.
