I have LDAC connected on my two phones and apt HD from my Bluetooth dongle. Never had issues with it. But I removed the sloppy spinning antenna and screwed in a giant antenna from Asus WiFi AC68 card. And yes, I confirmed with Topping. The spinning good for nothing antenna is by default on all of the units.
So, currently on the hunt for a valid alternative to see if i can I can improve my results.
