Some time ago, I did use my iPad Pro with Qobuz. It was directly attached using a high-quality USB cable to my Chord Qutest DAC (later via a Chord M-Scaler), and it sounded great. However, I then replaced the iPad with a dedicated streamer and the sound quality improved dramatically (with the added bonus that I could control my music wirelessly). In summary, the iPad sounded flatter and less nuanced. So for me, it was a big step up. Recently, I purchased an Innuos PULSE and the sound quality is even better now when I use the fantastic Innuos Sense app linked to Qobuz. I've even gotten rid of Roon! I suppose everything would depend on how resolving your system is but, in my case, the improvement was obvious.
