Has anyone tried the difference between a 2016 Iphone 4" SE's sound and the WIIM, because to my simple ears, the ancient Iphone SE's Dac sounds great, the Sangean WFR-28 sounds perfect, both analogue out (line out) to rca jacks to an old and cheap integrated amplifier/speakers, if the WIIM is able to match an old Iphone, then I can use it, I am slightly worried though that their Dac is inferior to an Iphone's, I think 99 percent of the Youtube audio reviewers are full of beans, every product they describe is great in most aspects (most of them come across as hack shills), I fear that the WIIM might sound like garbage without an external Dac, because even the Youtube reviewers acknowledge that the WIIM's internal Dac is just OK.
