Hi all, I'm using the Cayin N7 and C9 so I'm very curious about the Ibasso Combo D16 and PB5. Any comparison so far? Is there anyone try the Cayin N7 with PB5, Cayin N7 in pre-amp mode? I refer Cayin N7 because it's a DAP so no need additional DAP for reading file or music streaming. Tks in advance.
