Actually I have been temped to buy from Antipodes their DS series for years. But it has more function then I need the internal DAC and internal HDD plus all the ability for networking and multi-room. At one stage Antipodes has plan to release low cost model does not has DAC and HDD. But that has been dropped. I don't know when my Fiio X3 broken I might get Antipodes DS or Fiio's next DAP maybe it has USB out. Note: I don't like Fiio's internal DAC it sound sharp.
