Which gives better results inexpensive DAC or inexpensive tube Bluetooth pre?


I am an old school newbie when it comes to DACs and Bluetooth and still listen to vinyl cassettes and preferred tubes over solid state.  
I listen to Spotify thru an old phone or iPad plugged into my preamp via an RCA to mini plug, in addition to CDs, cassettes, vinyl and a tuner for sources so I am not into streaming yet.

i have friends who stream from their computer and are all about having a good DAC, but yesterday I met someone who had several amazing sounding systems and he had an $80 tube Bluetooth preamp in order to listen to his iPad wirelessly.  The several systems I heard yesterday are well above the lower end high end gear that I’ve had and just curious which is better - spending money on a separate DAC or a cheap Bluetooth preamp?  I like the idea of playing my Spotify wirelessly.  
I’m not ready for Roon, Tidal, a streamer or getting into it more as I have lots of music that I enjoy.  I’d just like to get better fidelity from Spotify and be able to listen to it wirelessly.  TIA :)

Thanks Rueben, is listening to my Spotify without a wire considered “streaming wirelessly?”  Because that’s all I really want to do at this time with better fidelity / the best fidelity available on a shoestring budget.
