Sorry - I am positive if I read the full thread - or even skim the pages - I will find what I am looking for... And I will tonight. But in the interim if someone will do me a solid... Would you recommend this for someone who wants a portable DAC/amp that does not care about (for now, anyway) the BT functionality? I have many IEMs (SE846 being my favorites) and full sized cans (too many to mention but from easy to drive th-x00 to harder to drive DT1990 Pro). I should note that I went in on the Kickstarter Hidizs HD1000 so that will come my way. But like we wouldn't have one pair of IEMs or headphones, why would we have one portable DAC/amp? If not the xdsd, what else should I look for in the $300-$600 range?
