I think in the hifi world there's such a perception / bias that the best system out there must be a beast of a thousand wires that that's what gets marketed to the audiophiles regardless of performance issues. It's the reason why smartphone headphone outs have gone the way of the dodo while poorly engineered DAPs that can't even shield their headphone outs from WiFi and Bluetooth, let alone 4G radio are ruling the earth, and TeraPlayer lookalikes (oh, btw, the TeraPlayer probably failed because it's too compact) that don't even have WiFi or Bluetooth knock even those out of the park in terms of sound quality in people's imagination. If you could spin a plausible story* around a 20kg brick that can only play wav files in alphabetical sequence, complete with loosely modular construction that falls into pieces at the drop of a hat, THAT will be the next holy grail of headphone audio quality, mark my words.
*The story of course being how every user-enabling feature out there is an evil polluter of sound that must be eliminated, because it hogs CPU cycles, dirties the power, etc. to cover up for the fact that the designers of this particular brick can't engineer their way out of a paper bag
