You seem to be well updated with your equipment. My candid advice...dump DAPs man! The Tidal App now does MQA on both PC and all mobiles and these devices do everything that a DAP can do and more! With a balanced DAC, i suggest use a direct feed from Tidal native app or Roon if youve got useless money lying somewhere) to avoid any sound coloration by the DAP. Just my 2 cents mate. I hope you work it out with the OTG should you continue that route! CHeers
I have collected almost every song I have ever liked (and I am 58) and continue to hunt for new stuff every weekend. My collection recently crossed the 6,000 mark and I love pretty much every song.
Except with Jazz. I have a TON of Miles Davis, but don't love every single piece.
I love my DAP for home and my LG V30 is for out and about. My music is all ALAC, AAC and MP3.
DAP to OTG to DAC to (2) amps to various headphones. Happiness for this guy.
Good luck with the DAC!
