Personally - I found the Thule Carbon Adapter is an absolute must, I would buy the Thule Carbon Adapter before the knob if I money was an issue - the adapter spreads the load more evenly across the clamping point - a test I did with standard knob & no carbon frame I clamped an empty deoderant can & found it easily left a dent in the can, with the adapter I went much harder and no dents so it definately works & safe to say without the adapter you are running serious risk of a pressure-point breaking The SQ out of the DAC is overall good enough but since there are no tone controls within the Qobuz app which I use most Im stuck with gain-HI and gain-LOW options only.
