Very detail review, especially the DAP comparison session, quite unusual to have such an extensive DAP line up in a tour review, I am glad that N5ii is lucky enough to be there at the right time.
I don't normally have quite that extensive a collection but it sure was nice to be able to do side by side comparisons with several of the top models on the market. I really do think that Cayin's primary competition at this point is Astell&Kern as the N5ii is very close to the AK70Mk2 in just about every respect. If the next generation N6 or i5 makes those last few tweaks to the OS/UI I think Cayin will be able to finally give A&K some real competition in the $500-1k range.
