Oppo has ended is manufacture of most of its audio products so you can only get the HA-2SE on Amazon or Ebay, for about the same price as a Chord Mojo. The new iFi xDSD is a reasonable current production option, with Bluetooth connectivity and a Burr-Brown DAC chip.
USB Type C! Micro USB isn't dead, so let's kill it. Oppo will sell more of these if Type C is onboard. Massdroppers aren't you tired of carrying different cables? Tired of fumbling and reversing Micro USB connectors? Tired of that weak micro size that is so fragile? Then ask for Type C on the Oppo.
I fail to see how Massdrop will be able to sell the Oppo when Oppo themselves are no longer selling audio products (including the HA-2). Having the micro-USB port changed on the Oppo to a Type C is even more unlikely. If Massdrop does get to sell it, props to them, it is a great portable amp (I got the HA-2 used and enjoy it a lot).
