Chain of command

Greetings,
     I have an ongoing lack of understanding about what piece of equipment in the following system, actually gives the music it's final quality out to my speakers.
  
**Thumb-drive with 48000Hz, 24-bit .wav music---to Samsung Android phone---analogue out of phone's earphone jack---to input on amp---to 16 ohm speakers.**

      Will a quality amp, tube or other, influence the quality, or is it already set by the phone's DAC?
      I only want to use the phone for it's interface to select my files to play.  I have read that any DAC connected to the phone's analogue earphone jack, ...will by-pass the phone's DAC?  This comment has been both substantiated and ridiculed, so I'm at a loss here.
      Seems to me that the earliest the quality is set, that anything after will just be upsampling.  
Is my most logical route to buy a DAC with a visual screen for file selection?

Any help here....would.....ah, ....help!
Thanks.

My setup at the moment:

Laptop > 3.5/RCA > Vali 2 > recvr >   /Grado/Sony HP / B&W DM600 S3.

The quality of the 3.5/RCA really does matter. Amazon Basics, once you hear the difference, just no longer cuts it.

 I am on a *very* tight budget and have found used high quality cables/interconnects here for *very* good prices, mainly because I have no problem using gear that may be a few years old.

Regardless, enjoy the journey. If you let it, it can be a blast.

I read somewhere where an Android (Samsung) phone, the Galaxy 7, puts out 16 or 24 bits, at 48 or 192kHz ...only, ...through the headphone 3.5mm jack.  If my music is 32f bits at 96000Hz on my thumbdrive then it will be demoted by the phone's DAC, correct?  Wouldn't anything after that, even a high quality DAC only be able to deliver upsampled audio?....which defeats the purpose.  (No, I probably can't hear any difference between the two. That's not the point.)  I use an OTG cable to get the audio into the phone.  Is there a way to send audio into the phone to be able to select the files, and still get it back out to a good DAC without going through the phone's DAC?

DAC can be headless, but will need to have some streaming features. Look for those that have a respectable App. Control will be via Bluetooth or WiFi or both. 

Thumb drive into the DAC. Phone for App control.
