I was considering this one. Tubes seem really interesting, it has a lot of features and price is fair but after I found out streaming is not an option (unless you connect it to your phone via Bluetooth and use it like a Bluetooth DAC) I changed my mind and got another one.
I own couple of digital files or CDs I ripped but mostly listen from Tidal or Spotify. I know, not everyone needs streaming but it's getting more and more present and Apple and Spotify will offer lossless means there is a growing demand so a DAP without streaming is totally OK but seems like deal breaker for most.
