I use the Audioquest Dragonfly Cobalt that's connected to my phone's USB C output via Dragontail, and is plugged in via mini jack into the AUX of my 2013 Toyota Tacoma. It's sounds a hell of a lot better than the stock CD or Bluetooth player that's in my truck that's for sure. I downloaded a USB bit perfect app to control both Tidal and Qobuz streaming services. You can listen to Hi Res FLAC/MQA music up to 96khz/24. I certainly hear the difference on the truck's JBL speakers.
Listening in car
I recently got a new car with a pretty good audio system and USB input. I want to use a memory stick/flash drive to give me access to many musical options. What's the easiest and least expensive to load music onto a memory stick? I have a Windows PC but, when I go to the music folder, there's not much. I have lots of CDs (now in storage because I now use an Innuous Zenith). Is there a way to transfer the CDs I previously burned onto the Zenith hard disk to a memory stick (I actually tried using a USB drive in my car made from the backup feature on the Zenith but my car would not recognize it). I can load some CDs onto my PC (which does have a disc drive) and then transfer them to the memory stick but it's time consuming and my stored CDs aren't very accessible.
