SevenLtrsWhat's your price range and do you want something portable or for your desktop? Picked up a refurbished Oppo HA-2 for $240 and it sounds amazing.
SevenLtrsI think you just missed the Centrance Dacport Slim. Not quite the best for using with an iPhone, but it sounds amazing coming com a laptop/desktop and is the same size of a thumbdrive. I've also had my eyes on the XDuoo XD-05. The specs are great and the reviews say they are pretty good.
