Soulnote is shipping version 2 of their A-2, D-2 and E-2 products, Integrated Amp, DAC, Phono Amp. Hideki Kato, Chief Sound Manager, commented extensively about the differences between the original A-2 and the new Version 2.
I copied his comments from Soulnote's FB page and created a PDF, attached in this post.
It's a super long read, but if you're into a detailed view of the changes from Version 1 to Version 2, as well as insight into Kato's listening-based design philosophy, you may find it worth your time. (I am not affiliated with Soulnote or any of its dealers - I do own a Soulnote A-2 Version 1)
TL/DR: Kato's conclusion is that the A-2 Version 2 is much closer to the original version of the A-3 than the original A-2.
