You could also use a line-out bluetooth adapter from a beosystem (maybe leverage a headphone out if no lineout) and connect to Phantom that way. Just find a acceptable output level from the bluetooth adapter and then use Spark volume moving forward. Not the best way, but a simple consideration.
Edit: the 6500 user manual shows it has line-out and headphone out. Not sure if the line out requires a proprietary cable, or accepts standard cables though. But there is the headphone out available.
