I am also still waiting for my v2+. Latest word is shipments will resume in March.
On the other hand, I love the v2 which I use in my car's media server, which sounds fantastic.
As for the v2+, the problems have been related to updating the original 3D printed case with something more attractive for which I am willing to wait
(of course, if this were for my main music system or something I use daily, I would not be this patient........i only use this when traveling on business/planes/trains/etc)
The current delay (adding I guess 2-4 weeks) is due to the shutdown of chinese production for the holiday (happy year of the monkey everyone!) and this affects the entire world's supply of electronics and parts from china. Sometime delays cascade and while it is never fun to be on this side of the delay, stuff happens (read the wonderful book/posting from the team at schitt to get a feel for some real world day to day hair pulling stories).
Could all this be anticipated? Could a small company guard against these eventualities while putting out a stream of new products?
Heck if I know, I'm a researcher not a manufacturer but I'm inclined to cut them some slack as a small company in a niche business dealing with us obsessive audiophiles.
Your mileage may vary............my 2 cents (with no intent to start/continue an even longer discussion)
