I am also looking into the AK70+Mojo pair myself, and Dignis sells a very nice combo case for it in case you are not aware. Same here, but of course all this is subject to what OpAmp you use for the Valoq.
Maybe that's an old photo of the prototype, someone did a backing and dial swap with an AK240SS, or a fake. As a side note, you can now buy the Blue Note version from AK for the DAP only without the MQS Jazz collection and books.
1, yes, AK Connect is WiFi only, but if I remember correctly, you can use it to download your library too.2, you are not wrong, and I found loading files into the AK240 (even the AK380 for this matter) is a pain in the ass. This is why the original AK120 with its dual card slot is such a God send.
