Don’t have a f90 yet but have a f85 with BO system. Your source is the most important if trying to truly hear the difference in the upgraded system
I am using Tidal and you can def hear the difference even with Bluetooth.
Biggest difference is usb connected
Not sure if a DAP is necessary. Just let the speakers break in and things will sound much better

I figure the BW systems is high end enough to maybe hear a difference and wanted to see anyone's experience?
