A quick question on what streamers to consider.......

+2 @ketchup   

OP, for background music out of doors, a decent Bluetooth device will work.  You didn’t mention speakers or source.  Presumably you will send the WiFi signal from your phone to a Bluetooth or AirPlay receiver but about speakers?

OP

You never answered some of the questions posed to you, such as do you have outdoor speakers? And amplifier?  It is difficult for @laps and others to advise you how to spend your money when the information is incomplete 

OP

your first post says you will be listening on your back deck (apparently from your living room speakers-not exactly the sweet spot) or while cooking in your kitchen (background music) or while entertaining guests.
When I have guests over, unless we are expressly listening to music as the main activity (a very rare event), my wife is usually dialing the background music into the inaudible range because the main purpose of being with our guests is conversation.

Likewise a quality component is going to be wasted on the patio, or competing with cooking noises. I mean, it’s your money, but most of the finer points other posters are making here about the differences in SQ between different streamers are beside the point for your application.

I use a CA CXN60 in my living room. The app works great, it sounds so good that I use one as a transport into a better DAC in my main system, it’s great with podcasts and internet radio ( which are excellent background listening choices while cooking). It has Chromecast and Apple AirPlay, which our guests use when they want to play us music from their phones, and I use for streaming Apple Music. It will natively play Tidal and Qobuz.

The Bluesound Node will fill your needs as well at half the price of the CA
