Help streaming Qobuz through Macbook Pro

I don't understand what you mean by "streaming from your iPhone to your MBP." If you want high res, load Qobuz on your Mac and connect it to your DAC with USB. This way you can do FLAC with as much resolution as your DAC supports, e.g., 24-bit/192 kHz. AirPlay 2 can do lossless 24-bit/48 kHz, which is good, but you can do better with USB. BTW, mathematically, the 24-bit is more important than increasing the sampling rate, but Apple Lossless may not be ideal.

I started this way too but I found it to be a bit of a pain and I wanted to be able to control the music wirelessly but still stream at high resolution. So I bought an Eversolo A6 but returned it for an Aurender a1000, which sounds much better IMO. These streamers sound great and are just easy. 

Pretty sure Airplay can't do hi rez just  load Qobuz on your Macbook Pro as lipdog suggests above and get your phone out of the equation.

You cannot use Airplay. It is a highly compromising communication protocol.. it doesn't even do anything well. 

It does not sound like you have a usb connection from your MacBook to your DAC. That would be a start... cutting Airplay out of the loop.

If you’re at all serious about sound quality just ditch the Mac and get a dedicated streamer that you can control with your iPhone using Qobuz at full high res.  It’s easier, more convenient, and it’ll sound better.  You can get a new Bluesound Node for $349 and be done with all this.

yeah what doglip say.

Just run the Qobuz app on the laptop and ditch the phone. 

I use a MacBook Pro via usb to my Pontus II.  I use the Qobuz app that runs directly on my Mac OS.  No iPhone or AirPlay required.  The Qobuz app will tell you what bit depth and sampling rate the song you are listening to is and your DAC should reflect the same info. This should be the link to get the MacBook Pro app.

I just went from streaming with an old macbook pro.( ethenet into mac, usb out to DAC) to a Wiim Ultra. Damn easy, great UI-updated regularly, well built. 329.00
