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

This is probably a dumb question with a simple answer I’m just missing, but here goes. I’m currently using my iPhone and iPad wired with a Camera Adapter to my DAC via Qobuz in my headphone setup and it sounds good, but I’ve wondered if using a streamer (on the level of an Optical Rendu or Innuos Zen Mk3) would be better as it’d be plugged directly into the router. I’d assume the latter would be better given the wired connection vs. WiFi, but wondering if anyone has compared that to connecting an iPhone/iPad directly to a DAC? Location isn’t a huge deal since I’m in close proximity to my router anyway. Thanks for any thoughts/experience/suggestions.

I just went through this and got a Pro-ject Stream Box S2 Ultra. It definitely sounded better than my iPhone. Other potential improvements that I've found to have good ROI in terms of improving sound quality of my Pro-ject streamer are:

1. Turning off WiFi and using an Ethernet cable
2. Getting a better quality Ethernet cable (Supra Cat 8 has worked well for me and was a notable improvement over an AmazonBasics Cat 6 cable)
3. Getting the right USB cable. The Phasure Lush is working really well in my system.

Thanks @calvinandhobbes.  Just curious what DAC you’re using and what kind of improvements you got with the Pro-ject?  I assume you were using the Apple Camera Adapter out of the iPhone?  Thanks again.

@soix I was using the Apple Lightning to USB 3 Camera Adapter with the iPhone. I'm using a Denafrips Ares II DAC. These were the improvements that I heard when using the Pro-ject streamer versus the iPhone:

- Broader & more 3-dimensional soundstage
- Better resolution of complex musical passages: Electric bass in Blue Moon Revisited on Trinity Sessions, Cowboy Junkies & Waltz for Debby, Bill Evans Trio
- Tonal colors are more evident
- Notes seem to hang in the air longer. Reverberations continue instead of being cut off.
- More presence around voices and instruments.

The improvements sounded quite significant to me & turning off the WiFi further improved my perception of the sound quality.

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....
