iPhone/iPad good as a source, or get a streamer?

Excellent feedback!  Thanks @calvinandhobbes.  I’ve been told by people knowledgeable in the field that a wired connection to the router is always preferable to WiFi, but there are also a lot of people here who say as long as you have a good WiFi signal and there are no dropouts that it’s just as good as wired.  The benefits you describe are very high on my “must have” list so I’ve decided to definitely give wired a try.  Thanks again for your very helpful thoughts. 

Just use the phone it sounds fine. I pretty much use an iPhone hooked to a mojo. The mojo poly looks nice too. It would turn the mojo into a “steamer” if you wanted. 
I failed a blind test of my Mac mini hooked to the mojo via tosslink and the mojo hooked to the iPhone. Hard to tell the mojo/iPhone from my benchmark DAC3 hooked to a Buruson amp too. I should probably turn in my audiophile card now....

@soix In addition to using an Ethernet cable from a WiFi extender, these are some other things that I did from which I heard a clear improvement. (i.e., so clear that I didn't even need to A/B test the sound quality...I knew right away)

1. I tried both an AmazonBasics Cat 6 Ethernet cable and a Supra Cat 8. The improvement with the Supra cable was about 50-75% of the magnitude of improvement by going to Ethernet
   
2. I added an Audioquest Jitterbug to the USB output from the Pro-ject streamer. The USB from the Pro-ject is supposed to be optimized for noise so I was more than a little skeptical of the benefits from doing this. But, the increased smoothness and clarity was evident.
3. I tried 5 USB cables (free USB cable from an HP printer to see if cables make ANY difference at all, Belkin Gold cable, Pangea Premier SE USB cable, Shunyata Venom cable, Phasure Lush cable). For an almost free option, the Belkin was okay, The Shunyata was clearly better. And the Phasure Lush was the smoothest sounding with the best resolution and the best at conveying the timing of the music. I LOVE the Phasure cable compared to all of the rest. The Shunyata is good, but the sound quality from the Phasure is at another level altogether.

I just been messing around with this on my iPAD when I discovered that on Qobuz app to get anything better than CD quality you have to download the track local. I am using lighting to USB A connector and Pangea cable. to DAC. The local files (>Redbook rez) sound purdy dang good but my dedicated streamer has a little more weight.
But I think for people with integrated amps and CD players with a DAC who want to get into streaming to test the water an iPAD is a great way to get started as apposed to buying a Bluesound Node. Which seams to be the default answer here when people ask about getting into streaming.  Then if you move up to a dedicated streamer you got a nice controller.

plug them into unused ports….
