I have apt-x built in to my Rotel amp. The Bluetooth works great for streaming from phone, laptop, tablet, etc. No audio issues that I noticed compared to streaming from the TV, listening to flacs from my hardwired media server, playing CDs, pristine vinyl, etc. But I still bought a Wiim Pro because when streaming from my phone or laptop over Bluetooth the music cuts out if I move rooms. And my notifications come through over the stereo.
