best source for Pandora

What is the best source for streaming Pandora?  I'm currently using a Kindle Fire HD 8 and an iPhone 8.  Is there any difference in the DACs in these devices?  Is there a better budget source with a better DAC?

I use a Bluesound Node 2 for Tidal Masters and Spotify but of course I can't get Pandora thru that source.

Thanks for your kind answers!
