Best player for Spotify

Hello to all. Forgive me if this is not the right topic for this discussion. I stream music quite a bit, and am using Spotify which my daughters gave me as part of a family plan. Right now , I am using my phone or iPad  for Spotify. I would like to use a dedicated "device." I would like to know some pros or cons to the following devices I am considering:  Sonos or Paradigm PW or Blusound Node 2.  If there are any other ideas you have that would be great. I am using a seperate amplifier and pre amp which are older and so does not have Spotify connect built in. Thankx,
Arthur
