Well, if there are no bugs ....
I'd love to see them make the Aux L/R outputs have the ability to be unity gain so I could use them to provide the input for my BHA-1.
My other idea was for Bryston to create a web-based interface to program the SP3, and have the web-based interface upload the information to the SP3. If it's possible, it'd make for a smoother user interface without having to recreate how the SP3 stores data.
