Lets revive this thread from the dead, got an email saying this is now on Indiegogo as Miu had a reshuffle in their office which delayed this project:   https://www.indiegogo.com/projects/duplex-world-s-first-portable-vacuum-tube-hifi#/
I haven't opened mine up to check the op-amp, but i will at some point. I've always been a fan of the LME47920 or LME49990 due to their very flat and detailed sound. I'll crack the HPA-2C open and take a look soon.
I think so, cosmetic changes and also they probably changed the quality of some of the components. Also the price is lower than the original and it now has a built in DAC as standard.
Check 2nd post for the review 
 Again this is from the product manager after I asked if the change had been made recently: "the new mechanism was updated when T 1 (2nd generation) was released."
I have just got a pair of these in the post, a bit behind on reviews at the moment, but will update shortly :)
