I've never used the PS audio Link or Dac Magic... I can't compare the HP-A8 with them. For the DAC section, I like it too. It is detailed, transparent, lots of air on the top. Bass is quick and well controlled. Not a lot of Bass.. Vocal is natural and just a little bit on warm side.
整體來說是自然,淡定,不溫不火.不象美國機 這類聲...
FYI, The above experience is only based on my headphones (not Speakers).
Hope it helps.
